Interesting though the posts have been, I'm a bit surprised this being an AH site, how little creativity there's been to have a RN 'victory'!!
A) The RN losses less carriers earlier - therefore more available in the IO in '42. Looking at what happened to the Glorious from an ATL point of view, the idea of it being sunk, could be said to be ASB - 'they'd bound to have recon aircraft up'.
B) A different mix of aircraft, is possible, though difficult without drastically earlier POD.
Hawker, made an unsolicited offer to the FAA of a navalised (Sea) Henley - with wing-guns, as a replacement for the Skua, as FDB - with higher speed and bomb-load - better than the Skua.
FAA decide to leap to the next level, with the Henley ordered, Fulmar orders are reduced, go next the Sea Dante (have used Dante previously so I sticking with it) a navalised version of the Boulton-Paul P.88A (though it does help it the RAF did order it in the first place - but it was thae Treasury who said 'no - so still plausible). Later versions with better engines, might well have taken over the duties of the Sea Henley, given their bomb lifting capabilities in addition to their four-cannon.
Any other ideas.
