Project Cancelled had an example of 2 AIR-2 on modified side pylons on the Lightning, though it is stated in the book that the intent was to only issue one per aircraft which would have most likely caused asymmetric problems. Totally academic as the defence council stopped all work on defensive UK nuclear weapons in 1960 due to lack of fissile material and decided that it would all be used for offensive stuff. Killed the Nuclear armed Bloodhound 3 as well.
