In a word ... no
The bridge and neck models have different outputs, so you'll not get similar results splitting the pair across two guitars.
I would ask Tim, he'll give you the answer one way or the other on price.
I would also recommend the Painkiller for high output - don't be put off by the DC ratings, output is all in the ear after all and my PK is just as loud, if not louder, than my Warpig.
