Jeese, you guys are no help at all.
(I was waiting to see what the more knowledgeable would offer.)
Rob, if you haven't left for good yet...
No. don't isolate the drums and complicate the situation by miking everything.
Put some treatments on the walls to kill reflections and damp the levels down.
Build a few gobo's to protect sensitive ears from sonic laser beams emitted by snare drums and guitar amps.
Play with placement to optimize everyone's rehearsing pleasure.
Oh, and ditch the electronic drums. They suck.
