Since the wooden part is now standing, I'll write down what I think needs to be done, what supplies are available and what is in need.
Here is the Current stand, with the planned separation of LCD and Power Unit:
Have a look at the PSU:

And at the LCD Unit:

If we want to seperate LCD and PSU and be able to attach and detach them quickly we need some kind of Bridge.
For the LCD Unit that's pretty easy. There are 2 pieces of 10p flat cables running from the control Unit, which is hidden behind the left side of the frame. So we will need 4 per printer.
2 Will go from Printer to our Bridge, then 2 aggain from Bridge to LCD Unit.
I have bought the Flat cable and both male and female connectors required.
My idea was to have a custom pcb as a bridge, we can make one from a temp PCB, but the rest we will need to order, if someone would be so kind to design it. Reason for PCB is because these female on-board 10p connectors or way cheaper then the loose ones, and We cann have all the Bridge Stuff at one location, and no cables floating around.
Here are some pictures of the stuff I've already aqcuired:
10P Flat cable (including diagram to make something simple look complicated)
Socket 10P
Plug 10P
I was worried about this one because bad connections are a fire hazard, but Danimo pointed out that we can just use WAGO clamps (WAGO 221-2411).
This is a fast, safe and cheap solution, we just have to make sure the cables are labeled, since there are 2 pairs of Red and Black cables and one braided Panic cable.
Here is the rack in both STL and Alembic, in case you want to design a door mechanism

About the doors, we currently have 3 large pieces for the Filament department and 3 large square pieces for the printer departments.
We can order the others once we have a working system
