I'm hoping to get into the Sonos ecosystem and can't seem to find much than conflicting or years old information.

I want to set up Sonos 5.1 (Arc/Beam) but use the surround satellites as side surround or at least high surround.

Reason is.... Hoping to use Amp/Connect as rear to hook up existing dumb speakers as rear surround at ear level.  I can't run wires to sides and want to clean up rear wires running under rug and instead have a wireless device in back

Is it possible that Sonos can send rear surround signal to the Amp (left/right wired rear) and then use Sonos Ones as side surround?

Any help would be appreciated
