You would lose some of the pulse tuning effect as velocities (and hence ram effect) would be lower, not to mention different resonant frequency interference from the side port and PP interacting.

If you look at the per rotor chamber intake volume there are pretty much no other functional engines (maybe a test rotary valve piston engine here or there, nothing brought into production) that has the effective intake area/ flow for chamber size of a decent PP intake.

Turbo charging doesn't change the basic fluid dynamics, but it does change parameters a little bit which will effect the optimised diameter/length of runners slightly. Obviously different intake:exhaust pressure ratios would have to be considered in terms of port timing.
