similar to a Garret 45 trim compressor wheel??

You are probably quite right, but what im after is a compressor wheel that
has a greater mass flow rate at say 100,000 rpm as the current 45 trim, but
with the same x sectional profile. Not too worried about whats happening in
the turbine at this stage.

Does that make sense?

I think the outside diameter of the wheel doesn't change only the inner
diameter (inducer). The inner is changed to have different trim's. Maybe a
housing with a greater a/r will work easier leaving the wheel as it is.
You can find some nice tech info here:
