Unfortunately it's not possible, as far as I know. You even have to preserve the original Soundflower (2ch) and Soundflower (64ch) interfaces for it to keep working.
You could use LineIn by Rogue Amoeba, which lets you pass audio from one input to one output.
It should be possible to launch more than one instance of it by typing:
open -n /Applications/LineIn.app
in the terminal.
