If you have "that many" (as in a lot) of requests, then you might be in a position to help your community. Assuming you have a good location for the repeater. You might have lost interest in it but maybe the inrush of "new blood" will renew your interest a bit. It certainly has changed from what you ol' timers in GMRS saw back in the day, but the new people seem eager to learn.
Apparently there is nothing wrong with starting a club and crowd funding new repeater hardware if the system you have in place now is not up to the task of changing frequencies. I don't understand the "hams" getting upset at someone else using the frequency. Hams have their own frequencies. A GMRS frequency is certainly not "theirs" in any shape, form, or fashion. Yours is also not a new repeater in the area, and you have every right to bring it back to active use. The repeater being used may bother others, but it would not be you who is stepping on anyone's fun rag chewing net. It would be your community, who has a lot of weight to collectively throw around as far as who gets to use a public frequency.
