Pairing Speakers - In Wall Center & Floor Standing HELP - Polk Audio

Hello

I am in the process of buying a 5.1 system components. This is the plan:

Polk Monitor 65T Floorstanding Speakers (2)
Polk SCC IN WALL Center Channel (1)
Polk MC60 In Ceiling speakers (2)
Sony STR-DN1030 Receiver

Does anyone see a problem with matching an IN WALL center channel with floor standing speakers?

Anyone have any experience with any of the above products?

The fact that you are keeping the brand the same is a big plus. Hopefully they are in the same price range and quality.
