Future Mesh Setup

Question?

I currently own the Nighthawk AX8 8-Stream router and would like to use it with another mesh system. Would it be compatible with the new Orbi WiFi 6 System AX6000 (RBK852)? I do plan on having either of them connected to my pc directly via ethernet.

Just want to know if I should go that route, if I can or should I consider the Nighthawk AX8 8-Stream Mesh Extender (EAX80).

Thanks in advance.
