More like a formation, then.
I know one of the dev's worked on a formation script (plugins/formation_tools.pl)
But, I don't know if those could be easily adapted for this purpose.
One of the first changes to bots that I'm going to implement is to save the bots follow distance so that it doesn't have to be re-assigned on every spawn.
I've thought about exactly what you're wanting to do..but, haven't developed anything, as yet.
As time allows, I'll see what I can do with this idea.
EDIT: Something like this..but, not so strict:
