There are many way to make it happen, but how much it will need time to work, is undefined. So I'll say you everything I do.
Here is the list of things that you can use to help you.
Make the VLA your least favorite gang.
Kill them a lot.
Be sure to have gang war acessible.
Use one or the two cheats, Gang are everywhere.
Use recruit anyone cheat.
Recruit VLA gang members.
When having a hood attacked by either Vagos or Ballas, kill the VLA you recruited or go to the territory and kill them there or keep them alive.
When having a territory attacked, recruit VLA and try the three steps mentionned above. (Kill them, keep them alive etc...)
Do the Hood Abuse glitch with the Satchel Charges.
Do the Airplane glitch. (Take a AT-400 or a Shamal and fly to the borders of the map)
One of those day, they'll attack one of your territories. When you see them, let them kill you, of flee away.
You'll see them hanging in the hood you sort of defended.
And sometime you'll see a Blue gang colored territory on the map.
I didn't tryed attacking those territories, but I'll try soon.
It could maybe work with the others gang. (Rifa, Triad, Da Nang, Foreli, Sindaco, Leone and the others I didn't mentioned (If there are others gang))
I'm gonna try it soon.
