My suggestion is simple and i will try explain it properly.
Whole suggestion is about Area Controlling(AC). Your gang could control some Area. It would have bonunes(like increase speed on map for players from gang or other things which we can discuss here in topic).
I have some examples how it will look.
Here i have example on map

Its only example(I dont mean Controlling VC), we would control Gordon Gas Station or Mariposa. This colorized squares you will can on/off by some button to show/hide them.
Whole Controlling procces will have same progress as in Town Controlling.
Info about AC will be in PipBoy too

I created this suggestion beacuse we, players what are interested in TC will have more options in PvP on server.
Those Areas will bring bonuses to gang(members) who controlling them.
Range of Area would be small, not too big.
