Yeah, it was suggested not so long time ago - answer is no.
Why not? Firstly you need to understand why there is random respawn. While you're taking the town and you die, you respawn randomly to not get too fast to this town where is fight. If you add a base respawn so every bigger gang would buy bases the closest as possible to the Modoc, Den, Redding, or any other able to control town.
That makes no sense and implementing base respawn would destroy whole idea of random respawn.
