Can I connect RBS350 to RBR750?

Hi, I'm looking to buy a mesh Wifi system for a house that is only partially wired for ethernet. I was thinking of getting the Orbi RBK752 system, which includes a RBR750 router and RBS750 satellite, to cover the non-wired part. Can I plug an RBS350 satellite into the ethernet to connect to the 750 router, to cover the wired part of the house? As far as I can tell, the systems are compatible except that 750 is triband and 350 is dual band. But will connecting the 350 satellite stop the 750 router connecting with the 750 satellite over triband?
