Ghost,
As I'd specified, Allied objectives could be as follows:
Five F4U squadrons to hit five sectors. Either a special V-1 object (could possibly treat it like a Shore Battery and attach it as part of a nearby airfield, vehicle base or port? That way it could be destroyable but not show up as a seperate map marker) or a Vehicle Base to substitute would be in each sector. If a special V-1 site is modelled and if it's small enough there may need to be multiple V-1 sites in each sector (say, 3-4) for the Corsairs to hit.
In addition to the Corsairs, the Allies would have a number of TBMs or jabbo F6Fs and/or FM-2s (keeping in theme with a USN/MC strike on continental Europe that was planned but never was) hitting other targets (Ports, airfields, strats, etc) in support.
The German defensive orders would ONLY specify to defend a given sector, containing the Allied objectives. That way, they won't know for sure if they're guarding against F4Us attacking V-1 sites, or TBMs/F6Fs/FM-2s attacking some other target.
Numerically, the Allies would have more individual offensive objectives, but owing to the potential small size of a custom V-1 site (rather than using structures such as VHs, which require 3000lbs of ordinance to drop, use ammo bunkers, fuel tanks, as well as a special V-1 launch rail object that could be put together to require a total of 1500-2000lbs of ordinance to destroy one site) this should balance out the ordinance weight required. Say, TBMs hitting two V bases at 9600lbs of ordinance, and the F4Us hitting 5 sectors each requiring ~4000lbs (1500-2000lbs per V-1 site, with 2-3 sites per sector) of ordinance (39,000lbs) Vs 5 CVs x 8000lbs (40,000lbs) for the Axis.
This should also keep the air-to-air side of things balanced as well. Because while the Allies have fewer objectives to defend, they'll need to devote more fighters to escort their strike packages, and vice-versa).
