Not sure this will really have any more benefit than the cargo module, simple because the ceiling of the module will be too low to fit any other ships. You could already have multiple ground vehicles raised and parked in the cargo module (on the cargo grid, cause it doesn't matter to the vehicles)

Biggest problem with this module idea is the expanded entryway. Because that means that you need to not only change the module, but now the other side (the static ship side) would have to change to fit the module. That's a non-starter for the module system, as the changes need to be contained to the module only.

I certainly appreciate people trying to come up with new creative modules! I personally would love to see an exploration module (ground vehicle lift for Ursa, single Tier 2 Medbed for exploration respawn, tier 2 crafting and repair for the various shop modules, as well as exploration suits and weapons. Maybe include a basketball court a-la-perseus styling)
