I think the single piston / 336x22mm stock rears would probably give the larger 4 piston calipers the best chance of having a decent pedal feel?
Also, would it give better bias by going back to the larger rear set up?

If you have small brake shoes 165mm and those rotors are from 330i or 335i and use 180mm large brake shoes so your parking brake won't function.
You car is e91 so is possible to have large parking brake kit from factory.
Single with 336mm will yield same or similar pedal feel with 2 piston 324mm
You can alter the bias with different pads. Don't worry much.
