However, the school wouldn't go back to how it worked back then. Instead, it would be open to everyone who wants to learn how to defend themselves and use their powers, not just children, and not just mutants (so, you could get Inhumans, or people who just got their powers in accidents, or extra-terrestrials - and turning 18 wouldn't mean getting kicked out). As others already suggested, past students could be teachers, like Dani, Karma, and Wolfsbane were in New Mutants vol 2 and New X-Men: Academy X. The generation who were there back then and never depowered are surely experienced enough to have graduated. So that's guys like Glob, Armor, Pixie, Rockslide, Anole, Dust, Surge, Gentle, and Kid Omega. Younger kids like Eye Boy, Nature Girl, Gabby Kinney, and Trinary would be students, but instead of being joined by brand new characters, some of the old ones would come back instead.
