It would open up so many more possibilities, even if we only had one type of landing craft that could only carry one GV. The way I picture it is you select the landing craft in Hanger, then, instead of choosing a weapons loadout like other vehicles/planes, you choose which type of GV to transport. Once underway, someone must join you to take possession on the GV. If no one joins, well, your stuck with an empty GV. Would be too gamey to allow the LC driver to switch and take control of the GV once ashore. People may say "Who'd want to transport someone else to shore and be stuck in an LC?" Well, I would.
