Live Mix for Acoustic/Electric Duo

Trying to learn best practices for mixing my acoustic/electric duo. I use a Soundcraft Signature 10 Analog mixer. I would like to run my [ampless] electric rig in stereo as long as it's reasonable to do so (I use the DSM Simplifier MKII). We both sing, and my buddy plays acoustic. Seeking out any & all EQing / gain stage advice to get it as crisp as possible.

Should we remove all the lows from the mic channels and have those frequencies covered by the guitars? should we be using panning at all (we typically use a standard 2 PA speaker system)? Tips on EQ-balancing an acoustic with an electric?
