Okay, I have a kind of neat idea but it'd probably be hard to implement.
The problem with reef is that it acts exactly like a repair pad, and you can build those yourself. So why not make it a specialist?
Give it a stockpiler like the screamer and drones that launch and instantly repair and reload any aircraft within the range of a defender from the carrier.
It could speed up time between bombing runs to near instantaneous.
You go in with one carrier with 12 stockpiled repairs and like four bombers to attack a line of annis, park the carrier right outside the anni range and it's like you have 16 bombers instead of 4, because they can attack, circle around and repair at the carrier instantly and bomb the next target.
This would fill a similar but more specialized role than the airpad, not just keeping planes alive but also increasing damage output due to faster reload times.
When enemies attack the group the carrier is in it could be especially devastating because planes could be reloaded and repaired the instant they take 80% damage or need reloading.
Actually it might be a good idea to have a seperate stockpile of drones to repair and drones to reload so they aren't wasted.
Of course, the stockpiling might take a similar time to a screamer so give the repair drones an on-off switch and give it a regular repair pad too so it can always help.
Other things that might help include but are not limited to=
- A very large radius shield that is centered far above the land so it protects far more air space than surface space. This would protect vs screamers and chainsaws.
-AA so your bombers can retreat to it
-Regular drones like we have now for defense
edit-
Maybe an air factory with limited production options too.
