Hello All, Looking for advice.

Current setup: I have a Sonos AMP connected through the ARC port to my LG TV

The Amp is connected to my 3rd party Kenwood Sub and also 2 kenwood L & R speakers on either side of the TV.

Proposed budget setup: 

I wish to get 2 sonos play 5 speakers to replace the L & R speakers.

Would this be a resonable setup?

Thanks
