I would just get a decent rack compressor, DBX, one of the nicer Behringer models, etc. Of course there are much more expesive alternatives, but the guitar has a relatively small footprint in the sound spectrum so a super high speed/low drag compressor isn't going to be needed for sound quality. Unless you are going for a super compressed sound that can be turned on and off at the floor level. "Real" compressors have always sounded better than any pedals I have heard/used. Depends more on how you want to implement it
