Upgrading brushless system

I want to upgrade my truck to an "overbuilt" brushless system, because my truck will be very heavy. I'm looking for something like a high turned xl motor, and a better brushless controller (rated for more amps).
I'm also looking for a lipo battery system (this is where the truck gets heavy). I run a pretty large BPP chassis, so I think I fit in quite a bit of lipo. Call me crazy, but I want 22.2 volt (18.5 nimh cell equivelent), 20,000 mah power system. I do indeed have the money to dish this out, so be creative:p .

I don't want to pull alot of amps, so maybe an 11xl motor and a 12020 esc?

If I find a system that works out for me, I will be having a Feigao 8xl (run very little), a 9920 (new, never even programmed), 2 pairs of fusion 8 cell straight line gp3300batteries (1 pair is a 1.75 volt spend $180 on it, and the other pair was 120). PM me if interested. Or give me an estimate of how much I can get out of all this on ebay.

Here is my truck so you can get an idea of its weight, and configuration (esc hasn't been mounted):
