The problem with X-School is that every game has done it. I'm bored with it. I'm so bored with. It's always the school. It's always Westchester. It's always New York. And in the past ... decade? ... it's also usually been Year One by a different name. And I don't like Year One, I never have. I've never understood why people love taking a character whose main appeal seems to be who they are and proceeding to change almost everything about them.
So if I were to toss my hat into this particular shitshow of a rodeo again after all these years, I would have to do something different. And different, to me, is Utopia. It's not just a different location, it's a different feel. For people who want Mutant School, that's still there, but that isn't the heart of it. This is a city-state, and a boat ride away is a city that thinks most of the X-Men are rock stars.
On the matter of continuity...
There was a game I played on years ago, and they had what I to this day consider the single best rule that I have ever seen on a canon, in-continuity comic game:
"No one cares what Iceman did in The Champions."
If you read a good wiki entry or two on a character, if you follow that up with a good mini-series or arc or a few one-shot stories about that character -- and you can find every single comic book ever printed online without spending a dime or going to a site headquartered in Papua, and anyone who isn't a piece of shit is gonna help hook you up with some great books if you ask them -- then unless it's a character so complicated that you need to have read Grant Morrison's biography to understand what the hell they even do, I don't think anyone is going to say "No, you aren't good enough to be in our nerd club house."
Does that help ameliorate some of your concerns about getting dragged beneath the waves of 50 years worth of comic books that are honestly not going to matter all that damn much beyond 'This is where we are, this is what we're going for, this is where these characters are at.'?
I don't mean that to sound bitchy, if it does - I've re-wrote it three goddamn times and I'm still not sure the tone is positive as intended.
