Bone question but what provision would there be in a Herc to accurately (Stanley is uncomfortably close to the aerodrome for any impact errors) bomb visually or on H2S equivalent? Also, I imagine that a low ingress and climb to release height would have been a bit interesting.
Regarding Nimrods, I expect JEZ' could have given a reasonable RADAR picture but with little provision for visual aiming; not forgetting no immediate equivalent to NBS. Additionally, I find it difficult to see how an AAR equiped Nimrod could perform as efficiently as a built for purpose Vulcan. I also remember that we we were still involved in a hide and seek game with Uncle Ivan at the time. That didn't seem to leave many gash MR/ASW assets to mod/retrain for mud moving, particularly as ASW FFs and SSNs were pulled from NATO task to go South.
