Question out of curiosity

Hello, I just discovered the existence of this app.
Currenlty I have the following Sonos setup:

- Sonos Beam
- Sub Mini
- 2 X Sonos one as rear surround speakers (setup in official Sonos App)

Would it be possible to use this is app to switch the sonos one speakers to front speakers and add 2 x era 100’s as the rear speakers?

Are there any disadvantages? Do certain things not work anymore?

Thanks in advance!

Kind regards,
Cedric
