How are you going to go about doing this? (package setup) What kind of FET's are you going to use?
GriffinRU: If you have look at my Quark case design, I am wondering how cooling all FET's very well will change current capability? I know it will probably ALLOW it to run to it's rated continuous current (most likely), do you think it could run a 2250 (with a bunch of added caps) in say a heavy 1/5, 1/6 scale on-road car?

I am looking at
IRF1324S-7 with 12 FET's total.
If you can keep temp low and under control then I do not see any problems with driving any scale model. But there is one thing which you need to consider, with every today's speed controller (with SO/SOIC) only one side has good heatsink, that means that only these FET's can be used in calculation for rated power dissipation (at elevated temp) and use derating factor as well. So if your quark has enough FET's to dissipated power of losses associated with 2230 motor at your working temp, then you should be Ok, otherwise that's would be your limiting factor.
