I know I'm not exactly an "active" member of the community, but I've been lurking here for at least a couple of years, and over at gamefaqs for a couple of years before that. I have a bit of experience with pixel art, none with spriting though. What I could do if it needs to be done is editing for the script, I have editorial experience, so I'd be good for the job, IMO. I hate seeing fan projects or translation patches with god-awful grammar, it makes it seem sloppy and amateurish.
Other than that, I used to be a fairly active member of the Cave Story modding and hacking community, and have a fair amount of experience tinkering with that data. I'm not exactly sure how close to that rom hacking would be, but if I could be pointed in the right direction, I could easily find out if I would be suited for it. I had no previous experience with that kind of thing, and I picked it up pretty quickly.
I'm in total support of the Aegis idea, too
