I could imagine unbolting the Vacuum Raptors and stowing them before you hang the can. (Once you have enough Raptors, you can redeem them for a free can!) They get packed as cargo in one of the non-can Starships and landed for re-use.

Maybe you vent the tanks and open a hatch on top, and there is a stairway inside with floors, ductwork, and places to clip on lights and electric outlets. Probably you roll out insulation onto the walls so you don't burn yourself or get frozen-stuck if you touch them, depending on what is going on outside.
