EX8000 X6s as an extender - Wired Connection

Hello I bought two X6S EX8000's extenders to connect to my X10 Nighthawk via hard wire. Will I still be able to create a One Home wifi network where everything still connects to the same wifi network but backhauls through the ethernet or does the One Home require it to connect via the wifi/wps? And if it can still do one home, do I just make them access points?

If it becomes a one home/access point, will alexa still be able to connect to different devices connected to it?

If someone could provide some helpful information  on creating a hard wire ethernet one home connection, if possible, it would be appreciated.
