I'm not sure that being NT for a day would make a lot of sense, so probably no.
The reason being, for instance if you blindfold a sighted person for a day, they still have no clue what it's like being blind. If a blind-from-birth person was given eyesight for a day, they would not be able to understand anything they saw.
So if you made an autistic person NT (or any other neurotype for that matter) for a day, the person would not experience what it's like to be an NT, because NTs are NT from birth and learn to experience the world as that neurotype. It's quite possible that an autistic person made NT for a day would be unable to function, and at the very least would get a skewed idea of what being NT was like, just as people who get themselves blindfolded for "disability awareness days" get a skewed idea of what being blind is like.
So, even if it were possible, nope. I don't think I'd be able to learn anything particularly useful from the experience. I would not learn what it was like to "be an NT," I'd at the most learn what it's like to "have NT wiring," and for that matter I would only learn what it was like to suddenly have NT wiring after never having had it before, which is different in the extreme from being NT from birth.
