I wish someone would start making little add-on boards you could put into your Sonos products to bypass the onboard hardware and use your own. Just re-use the amp, speakers.

I built my own spotify receiver using an rpi with a hifiberry add on which worked perfectly. If someone built even simpler custom made Sonos play:5 boards I’d be less reluctant to buy more of them as I fear they may be expensive bricks if Sonos fails.
