buy two behringer DI's!
I know they're shit but at least you'll be able to reamp and gain some isolation, mics on cabs will have lotsa bleed
EDIT: ok the bass player has DI output, so it won't be a problem that, just buy one DI and you're ready to go.
I usually only get a tiny bit of bleed in the guitar mics from cymbals, really not as much as you'd expect considering they are right next to the drums.
