When feeding the turbo into the s/c, you would want to have a turbo that provides enough airflow at the boost pressures the turbo ALONE will be providing to give you the total power output you desire.

The problem with this becomes if you can spool the turbo too quickly, you'll be providing greater airflow at lower rpms because the turbo will be providing more of the TOTAL manifold pressure. It becomes complex.

Boost control by rpm to limit total pressure early on can control that.

I was more or less being sarcastic. But it is interesting to think about the idea of twin-charging a twin.
