There is a Suggestion board where this topic is eventually going to be moved to, I bet. Next time post suggestions there.
The idea sounds nice except for the fact that it would, I think, eventually lead to copy-pasting the list of your faction member's alts who have been added to different bases and so technically belong to different gangs, which means it would give another reason to play the game not like the devs originally wanted, instead of giving a reason to play it like it was originally thought.
