I'm looking to replace my hub router (connected to upstream ISP, and feeding some local devices with CAT5). And I want to use my X20's as wifi extender's, without being directly plugged into the Hub router. Perferably set up as one singluar Wifi network between the router and X20's (not multiple networks).

Does the OneMesh feature allow me to do that?

Would a TP-Link AC1200 work for me in this situation?
