Unless you have a fox talas or rockshock u turn system which you can adjust as the mood strikes, I'd be inclined to go with a reba set at 115mm or a fox set at 120mm before going up to 140mm of set travel.
I've put a revelation for two years on a '05 Commençal 4.SL and works without any problem. Only shortcoming with 130+ forks is that the front lifts much easier, so you have less control during uphills rides (U-turn helps though).
I've installed a pike on it for a severe competition.. I'll try it, but, as brocelif confirms, I'me confident...
