Cobra Automotive has a kit to mount two Paxtons on the front of an FE.
If you haven't bought the blower yet, you could probably get their cooperation in supplying you with the needed bracketry if you offer to buy a blower through them. You're basically looking for the same setup as a dual-Paxton FE, just replacing one Paxton with an AC compressor and the other Paxton with one large enough for your purposes.

I think ERA also has just completed a dual-Paxton cobra, so they may be able to help you as well.
