Possible to Use RT-3100 with Orbi RBK50?

Hi SNB'ers,

My main setup has been a RT-3100 with a Tmobile Cell ac 1900 Tower router Flashed with asus softare so I have a good AI mesh setup.

This week I was given a orbi (1 router, and 2 additional orbi's), and I'm wondering is there a way to make these routers work together, and is there is any benefit to having them work together?

I get about 150mbps, living in a single story home almost 2k sq ft.
