Considering a window AC with an "isolation box" for my small basement studio

I am in the planning stages of a small basement studio and would like feedback on my simple HVAC idea. The studio itself will be a 12x14 foot room in the corner of the basement and I am planning to isolate it fairly well (resilient clips and channels facing the ceiling and the two interior facing walls, two layers of drywall with green glue). It's a small space but I plan to treat it well and it will mainly just be used for my personal recording projects. The room will have a solid-core weatherstripped door leading to a short hallway and then a second solid-core weatherstripped door to the rest of the house. Off the short hallway will be a small 6 foot by 8 foot room where I plan to show off my guitar collection. My concerns are getting fresh air into the room without compromising the isolation, minimal cooling (it's a Portland basement where it usually stays pretty cool but I'm guessing with the heavy amounts of rockwool I'm gonna have and equipment running I'll need something) and dehumidification (both in the studio and the next door guitar room - I've been measuring 70% down there and want to bring that level down for my guitars).



So here's my plan: I have a standard basement window high up on what will be the rear wall of the room which I'm thinking of removing and retrofitting with a window AC/fan/dehumidifier unit such as this one Shop Keystone 6,000-BTU 250-sq ft 115-Volt Window Air Conditioner ENERGY STAR at Lowes.com

I'm hoping the size of that unit should be enough to cool and dehumidify the room as well as the small adjoining guitar display room I am planning.



For heat I will simply use a small thermostatically controlled baseboard heater on the floor below the unit.



What I want to then do is build an "isolation box" - I'm thinking maybe a "sandwich" of two layers of MDF with leaded vinyl in between to mount on the wall over the opening with the AC. The front of the box will have heavy duty hinges and lift up on those little thingies like they use for car tailgates. When closed it will seal like a tightly weatherstripped door.



When I'm not using the room I can leave the box open as well as the door between the studio and hallway (the door between the hallway and the rest of the house will remain closed) and the system can keep both rooms conditioned as designed. When I am using the studio, the door to the hallway will typically be closed for isolation, and I will turn off the unit and close the isolation box, but will need to take a break occasionally to open the box and run the fan for a few minutes (as well as the AC depending on the temperature). It's not a perfect solution, I know, but in my mind it seems fairly simple for a DIY project on a budget.



I'm seeking feedback on the following: 1) How does this concept sound in practice? Will it work OK? Any better ideas? 2) How does the isolation box idea sound as far as keeping the integrity of the isolation I will have achieved with my resilient channels/double drywall/green glue, and 3) What ideas do you all have for mounting the isolation box? It will be up high on the wall, the construction will be heavy and it will pretty much have to be touching the ceiling overhead which is intended to be "separated" from the wall with the proper gap/caulking and suspended on resilient clips/hat channel?
