	If I could add my own piece to the pile [i](I hope I'm not overstepping my bounds or anything)[/i] I think Etherian has a point. Having Sans around as a player character would be a lot of fun given his personality [s]and god awful puns.[/s] However building him off how he operates as a boss might not be the best approach. One-hit kills are problematic. If he's caught in a situation where he can't avoid damage then he's toast and that might not be as rare as one might assume. 

	There's also the fact that this is 'player' Sans and not 'boss' Sans. 

	In the Genocide route Sans is only a one-hit KO enemy because that point you're OP as hell. If you look at him from a grounded power level then Sans would likely be fragile, but not killed in one hit. 

	I'd like to expand on this more, but I have physical therapy and need to go now.

because of how the stat system works they could effectively build sans as an incredibly fragile char by having only 1 in both defensive stats and putting almost everything into dex. thus making a Dies in one hit rule a bit redundant. 

I would like to note that in undertale San's hp is 1. this is in the game files if you data-mine them apparently so in universe sans would in-fact die from any hit that does at least 1 damage. Which I imagine is most of them. Not an argument for putting that mechanic in I just  thought I should note that fact for the discussion.
