The next day the principal, Mr. Nolan, would have been fired because he couldn't keep control of his class. Mr. Keating would have been re-hired, and the kids would have had him back for a teacher. Kris and Knox would have gotten together. (:
I think that they boys would continue the Dead Poet's Society meetings in Neil's honor. I think that Cameron would transfer to a different school because he wasn't very well liked after ratting out all of the boys.
All in all, I think the ending could have been better than what it was. I think what I have would be a great alternate ending. (:
