For a studio in the box, it's really best to have all the gear in one room. The only thing I would use 2 rooms for is sound isolation for recording, or to listen to the music in a different environment on a different system.

Trying to control the system remotely would be IMHO, and exercise in frustration. I'd find a way to keep all the studio gear in one place.

In my system, for example.... I have one computer and one interface and a pair of monitor speakers setting in a corner of a room. That's all my studio is currently comprised of. I have a stereo system connected to one of the interface outputs for the rare times I want to check the mix on a nice consumer grade system.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
