The problem with the internal landing bay is not only the circular shape but the fact the control room must be in the middle.
It can be done with enough space: Below is a plan with a 120m diameter breathable area (the circle).

The 2 triangles are 25m across, roughly a DG. The green is the control room, the blue are inflatable habs (to fill up space). The purple is a cargo storage area or parking area. The brown/beige is a vehicle door.
The floor would have some sort of roadway pattern from the door, past each glider off to empty space by the habs.
