Disjointed thoughts:
Autonomous ops by the RN would still be possible within range of land-based AD, though if you can see Tony Blair or his successors undertaking such ops, you're either a visionary or a lunatic.
Outside the range of land-based AD the RN would require AD cover from coalition allies. But aren't we supposed to be moving away from Deep/Blue Water ops into an era of littoral warfare?
I don't hear any of the 'must keep the SHar - it's a national capability we must retain' complaining that the RAF requires allied SEAD support, and other capabilities, every time it is used.
Yes, Turkey proved difficult this Spring. Did that prevent the op? Did that necessitate the deployment of SHars? Or did we just use bases in Kuwait, Saudi, Oman and Jordan?
Were it possible to guarantee the availability of two carriers simultaneously, FEBA's two carrier solution would be interesting, since a two-carrier group could do both roles simultaneously, making it useful.

Blue Vixen or APG-65 on GR7/9 would not be practical or cost effective.
