Theos and fresco's as surround (Atmos) channels

[violinfather]

I just purchased some Theos and have been offered what I think is a good deal on seven fresco's which I would like to use as surround speakers. Would these be okay as a sonic match as surrounds?

I'm not sure if they would match or not. I'm going through the Atmos speaker selection myself. I'm questioning how critical matching is for the top 4 Atmos speakers. In my current setup the 7 speakers are all matched and modes like 7 channel stereo work well. I'm not certain yet how the Atmos speakers are used in non-native Atmos content.

I'm almost thinking that I just need to buy some and hear how they sound in my environment.
