Is it possible to combine the WPA8631P powerline adapter with the Archer AX20 using onemesh?

I understand I will loose the WIFI 6 when connected to the powerline adapter, but I want to us it upstairs, just for connecting the phones, so they can switch between the powerline and the router seemless.

I already have a TL-PA8030P KIT in use, so I want  to extent the existing wifi via powerline, but I don't know if it is possible to use onemesh between wifi 6 an wifi 5 devices.
