It seems that a couple of auto manufacturers had done this. Both Nissan and Lancia had built cars that used a turbo in front of their blower. The Lancia Delta S4 and the Nissan March ST had similar arrangements.
Here are a couple pictures, one with a rudementary digagram of the idea, and one of what they did on the Lancia.
Some things to consider.
Location of throttle body and MAF.
Bypass valve for the turbo to go around the blower
timing and sizing the turbo to complement the blower.
