Just thinking a little more about docking. You really would not need to give up mobility, as long as all the ships docked have engines you would basically get an average speed of all the ships combined. The other thing is you could exceed the maximum vehicle size and build enormous ships and bases, kind of like the Ultimate Vehicle Size Mod. That would make for some wide open games, you would never know how big a ship or base was that you were facing until it might be too late.
