The Vigilante was a decent kite, at least in the latter recon variant with increased range; but IIRC it didn't have a conventional bomb bay, but a novel affair where the nuclear load was 'extruded' out the rear (no comments
). The wing pylons carried fuel tanks but I don't know about being wired for weapons. Out of all the contenders I would opt for either the FIII or, a developed Buccaneer: more powerful engines, stretched airframe, new wings, and avionics. I have a drawing of this if anyones interested.
I liked the Hustler, one of the most elegant looking bombers of its day, but I can see why it wore out with low level operations. Maybe over the Artic it wouldn't be such a problem if you're looking at a standoff role beyond range of Soviet shipborne sam's? I can just see a Swedish badged Hustler
