Orbi comparability across models

[Jonnybunker]

Hey all - I have the following setup and am wondering what my best moves would be.
I have
-RBR50 as Router
- RBS50 as 1st satellite
-RBW30 as 2nd satellite
-SB8200
-Comcast Blast Pro
-3000 square feet house , 3 floors and about 45 total devices including cameras , smart devices , streaming etc

I want to add more coverage as my nest doorbell is now dropping on and off and want better coverage in my front yard and back yard.

Can I get one of the new Orbi Wifi 6 Router and Satellites and still use my 2 RBR/RBS 50 as satellites to get better coverage ? I am fine not using the W30 as I have heard that could be slowing my whole mesh down!

30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router
