Is it possible to create 5.1 SS with Sonos Arc, 4 Polk in-ceiling speakers/sub already installed, and a Sonos Amp?

I think you will have to start working with Sonos as it is designed to be used.
The Arc does front left, centre and right. The only usable subwoofer with the Arc is the Sonos Sub. For the rears you can use an Amp plus passive speakers or a pair of Sonos powered speakers. That's the design.
