Not sure I like that idea but what about if there were areas of camoflage netting spread around the VB, open in different directions for defensive purposes and big enough that a plane would have to guess where or even if you were under it.
Also, instead of blowing up and burning, when hit by a bomb it would simply tear an opening or possibly even collapse one corner. You on the other hand, if hit by the bomb would suffer normal damage/death.
These could also be placed strategically just off-base.
AA vehicles would still have to remain in the open or just at the edge of the nets for a clear shot.
