Why not take the simple route:
HTC requires that each map has an area surrounded by 40,000 foot mountains, it only has three bases (one for each side), The bases allow you to only up fighters, all ordinance is disabled and no GVs. In addition, you make the ack über TM deadly and accurate to discourage vulching/de-acking. Furthermore, you make the FHs indestructable. Clear the areas of trees, make it a flat as possible, put the bases no more that 1 sector apart and the whole area no bigger the two sectors by two sectors. Finally, you make is so these three fields are not included in the count concerning winning the war.
I know it won't happen, but it would sure settle a few things.
