Additionally, if there's any latency between the two it could potentially sound a bit funky.
Also, you'll definitely be capturing the snare in your overheads, too, which will give you a louder, very "room-y" sounding snare coupled with very dry, up-front toms and kick. It could work, but most likely will just sound unnatural.
I'd go all electronic, personally.
