I called this concept Tilistation, and you can see the mockup here.

I've been attached to the idea since, but I'm neither a coder nor a mapper, so my abilities were rather limited. Still, I found myself revisiting it the other day, with a number of things about the stations we play now being very different, and thinking - hold on. There's another idea here.
Below you'll see a variant mockup with more blocks. It doesn't have the shuttles and the solars, but perhaps the scale is a little more clear in this recent example I've been tinkering with.

What I'd thought of was this - if each department is consistent in size, shape and placement, then why can't we have this sort of station where the placement of each department is randomised in each round?
Take the second image, for example. The departments are roughly colour-coded in ways you'll probably mostly find recognisable, and that's the way I put them on there according to a rough logic - but what about, by using a system similar to how we place objects and ruins etc. roundstart right now, making each block department randomised depending on a rough logic of its own? As examples:
- Arrivals, departures and cargo bay will always need to be placed next to space, and their respective shuttle docks will be there as well, on the adjoining section of hull across the corridor.
- Command and the AI core will always take one of the four centre blocks.
- Engineering will need to be next to open space. This station was designed with solar arrays in mind, but building an engine or using a turbine is entirely feasible.
Departments that require an external dock would have airlocks in the large external maintenance tunnel opposite them, like virology or xenobiology's mantrap airlocks, but lacking the lockdown cycling.
It's a pipe dream, and I lack both the time and expertise to do it, but it's been bugging me for the last little while, so I figured I'd throw something down on Paint to show what I meant, though I know nothing'll come of it, probably. Hell, I'm still attached to the 9/16-block literal metal box-station idea even if the randomisation is unfeasible.
