OrangePi as Bluetooth Audio Receiver

I have found this interesting how-to, and I was wondering whether this could be done with DietPi as a base:

My goal is to create a machine that runs the Logitech Media Server, Squeezelite AND that can be used as an audio receiver (basically like a bluetooth speakers set).
I guess the main problem would still be Squeezelite monopolizing the audio stream, though.

EDIT: I don’t actually need LMS+squeezelite as long as I can find a way to play music files from a NAS and radio streams (TuneIn?).
Could another possible solution be PulseAudio + Mopidy + Mopidy-TuneIn plugin alongside the aforementioned tutorial?
