in most cases (not always), drums are more towards the center of the mix, and bass almost always is. If you could find a way to extract the side channels of the song you are looking to work on, it should take out some of the drums, but it probably wont sound too good without the center channel there. Adobe Auditions has an effect that extracts the center channel of the mix, but I'm not sure about the side channel. you could also eq some of the bass out without affecting the other parts off the song too much, but eqing drums out would be next to impossible. Hope this helps.

As far as I know, drum edits are usually done with some EQ to cut out the low end of the original track, along with some ducking to layer your own drum hits in there (usually sidechain compression and stuff like that). I'm not entirely sure though, so if someone has better info I'd defer to them.
