How about a kind of capture the flag!
Spawn points moved further apart, the flag would spawn, vanish and respawn every 20-30 minutes or so. It would be a variable spawn similar to what we have now for GVs. The object would be to capture the flag, by driving onto it, it would automaticaly attach to your GV, Then you would have to make it all the way back to friendly large pad to win. Win what you say? how about perkies for every friendly GV within 5K of the flag!!

Also the flag could be invisible to aircraft whether it had been picked up or not!
