Pairing with LS50 for whole home audio

Good morning all,

I’ve got a room I’m trying to build for some high end audio enjoyment. I’ve got a Rega P3 turntable and recently donated my NHT classic fours to my downstairs home theater (man do they sound great). Now I want to buy some nice hifi to restart my system. I’ve got a bead on a nicely priced pair of KEF LS50s and was thinking of pairing with a Rotel RX-1052 and a klipsch sub from the 1052’s pre-out

My room is about 12x15, I listen to mostly folk/Americana/oldies/country/jazz witn some hip hop and rock mixed in. My wife would like the system to be able to run  into another set of speakers for the kitchen/living room and have the option for Bluetooth streaming audio. 
My thought was to get the above setup - P3, RX1052, LS50s, klipsch sub and pair it with a blue sound node, then attach a Bluetooth transmitter into the zone 2 of the amp, sending that to a Bluetooth receiver on another amp in my kitchen/living room and potentially into my basement home theater system. Anyone have ideas on improving this particular setup without dropping $5k?
