Actually, there was such a proposal - but Sharkey Ward got the wrong end of the stick entirely...
Ward thought this a sign of the RAF's malign intent, when in fact the proposal came from Professor Eric Grove (made with his tongue planted firmly in cheek). This was part of Prof Grove's rejoinder to the idea that the RAF should be broken up and divided between the Army and RN.
Grove is not serious about this - his point is to suggest that the UK's security needs are very dependent upon air and maritime power, and less so on land power - so his case is very much a 'if you are doing to do something damned stupid, dividing the army between the RN and the RAF, while equally damned stupid, at least pays heed to the primary security and defence needs of the UK'. He put the proposal forward in a paper, an now contained in a book on SDSR, for RUSI.
What happened next, AIUI, is that a certain Air Marshal (Harrier mate, name rhymes with 'talker') learned of this suggestion, thought it amusing, and thatit might be good fun to wind up some Army types by putting Eric Grove's cunning wheeze forward as banter. Which, again AIUI, he did.
This, of course, ended up with someone in green thinking that this was the sign of an RAF plot to disband the army, and the news got to Cdr Ward. Credulous as ever when it came to something which could discredit the RAF, he believed it absolutely and put in the FOI request...
(It should be noted, of course, that although Prof Grove is critical of several elements of the light blue approach to things, he is an absolute advocate of the existence of the RAF as a separate service. He is also, of course, one of the nation's foremost maritime historians and an enormous fan of the RN, so hardly an ignorant dupe or a light blue stooge)
