I actually thought about this, robots just customizing themselves to suit the situation. But the players having a bajillion equipment sets would just be taxing to me so I restricted it to a set personal equipment that the character takes during all missions. It also wouldn't be fair to the current players so I recommend just going Hybrid if you want to be versatile.

The in-universe explanation would be that technology for customizable robots is extremely limited for now.
