I took my RG550 all apart a few weeks ago to put a new pickup in it, and I pulled the bridge to get the pickguard off. While I had it out, I just got a piece of black stick on felt, cut it to the shape of the bottom of the trem cavity, and stuck it in there. It looks LOADS nicer now, so if you do end up thinking that your route is too long you could do that and i think to most people the issue would all but go away.
