Ed, I know a larger turbo overall will add quite a bit of lag. If you use a bigger compressor wheel you have more mass to spin up, etc. What I'm proposing is to only upsize the turbine housing to what the 9000 aero used. What's 1 cm^2 larger area between friends anyway? The stock compressor wheel is fine as far as flow rating goes, by what I've found on the net. Even if it goes out of its highest efficiency range, a good aftermarket intercooler (like yours) would cancel that out. You have EGT gage, right? How much do they run? I'd love to buy one and do before/after dyno and EGT when swapping out the turbine housing. I woudn't mind losing 200 rpm in spinup since when you accelerate and change gears, you don't drop rpm's below 2,500-3k anyway.
