Then you'd want a centrifugal blower. They come with one. Additionally, if you use a big enough centrifugal supercharger and put a slow-enough pulley on it, you can keep the torque curve at a manageable level for the entire powerband, and avoid having to have new driveline and transmission costs go through the roof.

The torque curve for each is the line that starts out higher than crosses over to lower than the hp line in each color. Considering the less-than-wondrous exhaust port layout of the 3.6 (the only thing I don't like about the engine,) you could just slap a Procharger on it and then tune the pulley size to give you a torque curve that was fairly flat, so no sudden 900 RPM torque spike to break the stock driveline pieces.
