How does this sound. For an excessive cost of gang points, a gang can view an opposing gangs hideout condition/rating. After viewing, the gang can then choose to "help" the other gang by contributing in the refresh of their hideout. In turn allowing the spying gang the ability to declare on said gang in surprise fashion.

Maybe the gang that is being spied on will have their Pres get an event notification that their hideout has been infiltrated. If he is not online then the gang is not notified and will be effectively worked. If they are online then they can do the necessary things to fortify thier walls.
