Maybe he could start a new life as a clown.

Rainbow-haired rapper-turned-stoolie Tekashi 6ix9ine could enter witness protection now that he’s done singing against his former pals in the Nine Trey Gangsta Bloods, prosecutors have said — but the instantly recognizable fame hog would have a hell of a time living a secret life, according to experts who suggested he go somewhere no one would know him — like Amish country.

“We could put him in a place like a Mennonite community or the Amish where they might not listen to rap music,” said former Rhode Island attorney general Arlene Violet, who co-authored “The Mob and Me: Wiseguys and the Witness Protection.”

Still there are hundreds of reasons that conservative dress and a chest-length beard couldn’t keep Tekashi blend in — the more then 200 69’s he has inked across his body, including his face.

Fully removing the scores of tattoos could be an extremely painful process that would require years of treatment and leave tell-tale scars on the tattle-tale rapper, one expert said.

“People try to burn it out or surgically remove them and all those things will get the ink out, but the problem is that it’s opening the top layer to get the surface, so it causes scar tissue,” said Jeff Garnett, co-owner of the tattoo-removal company Clean Slate Laser, which has locations in New York and New Jersey.

Getting Tekashi back to a clean slate is “never going to happen. There’s always to going to be some sort of pigment,” added Dr. Jeremy Fenton of Schweiger Dermatology Group in New York, who added that lasers will leave behind faint markings that “will fade over time. Your body’s immune system is what is actually removing the ink.”

But Gerald Schur, the founder and former head of the United States Federal Witness Protection Program, said the feds have a trick or two up their sleeves that he declined to share.

“With the tattoos, I cannot tell you what we do with them,” he told The Post. But “[t]hat’s not a problem. They can be dealt with.”

Violet suggested he find a gig that lets him keep covered up.

“He could do it successfully as a monk since they have clothing that would hide the tattoos that he has now,” she said.

Even if he manages to look unassuming, the outspoken rapper will have to learn to keep his trap shut if he wants to fly below the radar.

The 23-year-old Brooklyn rhymester can expect to be flung far from the hip hop world — and handed many non-negotiable rules that has leaving rap behind at the top of the list.

“You try to find something they can do other than” their previous gig, Schur told The Post. “We decide on the basis of what job skills they have — if any.”

Since the secretive operation launched in 1971, more than 8,600 witnesses and 9,000 of their family members relocated with new identities, according to the US Marshals Service.

Mobsters have started over with new names as restaurant managers and their associates have lived in plain sight as accountants and even company presidents, experts said.

To be offered federal protection, Tekashi would sign a memorandum that “sets out what his life would be like” and outlines expectations for discretion, according to Schur.

“If he does anything to expose himself, he’s out of the program. That’s in the document,” Schur told The Post.

There are obvious and enormous risks if he were to leave the program or reject its services.

“One has been killed. He was told not to go home he went home and turned the doorknob and it blew up and killed him,” said Schur, who co-wrote the book “WITSEC: Inside the Federal Witness Protection Program.”

To best construct his new life, Tekashi will be examined by a psychologist, take diagnostic tests and work with employment specialists, according to Schur.

He and his family will also be given new Social Security numbers, dummy medical records and financial stipends for six months.

The federal marshals will also help him move furniture, provide career training as well as therapy to deal with mourning his former life.

It’s they’ll want him to be somewhere he can pursue a career that interests him, Shur said.

“It’s very difficult to make people want to stay in witness protection because it’s hard to get them excited about them flipping them a burger if that the only skill they have,” Violet told The Post. “You look for an aligned field where they don’t work as a rap singer, but they know how to do the drums.”

Most of the people in witness protection have led exciting lives involved or adjacent to crime — and can be resistant when it comes to a quieter life.

“The single most defeat of this program were the people who were used to limelight and notoriety — the big-time gangster members with the media snapping their photos when they walked into court. They missed the limelight and it became too dull,” she said.

Given his fan base, Violet said that Tekashi will need to commit to the rules of the program and “not get up and do karaoke,” she said. He’ll also have to shut down his Instagram account where his online antics have racked up more than 14 million followers.

“He’s got to watch his need for notoriety,” Violet said. “He’s got to curb that since his number one danger is seeking the spotlight.”

She said that the federal marshals will sit down Tekashi and brief him on the dangers that he faces based on their own intelligence.

“He’s got to make a mature decision of assessing his chances of survival,” she said. “He has to listen to people who know more than you do.”

Despite the obvious challenges, federal marshals will be undeterred by the prospect of hiding a multi-platinum-winning rapper with millions of Instagram followers.

“They like doing a tough case and be able to say we were able to get him away,” Violet said. “They have justifiable pride in the job.”

Tekashi’s lawyer, Dawn Florio, said that “no decisions have been made” as to whether her client will accept federal protection.

“No one can be forced into it,” Florio said. “It’s a decision that has to be made by the client and they also have to be approved to be in [the program].”
