The firmware won't care... you'll need to turn the appropriate extruder motor in your gcode instead... which should be E0 (or just E) and E1. The firmware for the 3DChameleon will still only have 4 positions, but it never knows what you're doing with it, so the E value is irrelevant to it. In your gcode, if your next_extruder is <4, you use E0 and if it's >3 then the it'll be E1.

I might add, as Tom Rich pointed out, my suggestion would actually work for Klipper... however.
