They could honestly just replace all of the high tier maps with EC if they balanced the maps out. The EC maps use the sim spaa which are very powerful. This means that planes like the a10 and su 25, plus any jet without ranged weapons, are not able to effectively engage ground targets.
For base bombing, they could leave the current system in place but port over the sim airfields. This would allow for bombers to still have a solid target and give them the ability to help the battle effort by limiting the repair and rearming abilities of the enemy.
