It's for the best, I think, to stick to 1-mutation per mutant. It serves neither a character nor the concept of comicbook mutants well to expand upon that. Logan has his healing factor, done. His heightened senses, if I recall correctly, seem to have been written by Chris Claremont as super-human -- but it would be good to back away from that. Not everything about a mutant superhero should part of the mutation -- e.g., Wolverine was subject to bersker rages, but that wasn't a special mutation.
Interesting discussion. Though I suppose it's a bit of a stretch, I felt like heightened senses and healing factor fell under the same umbrella of enhancement of existing human abilities.
But honestly, outside of sense of smell, I hadn't seen much done with the other senses.
Something that I found of interest recently, was how long it took before Wolverine was shown to have any mutant power. He definitely seemed harder to kill than the average person, but his healing factor wasn't ever really spoken of until X-Men 116. Xavier said he was a mutant but what his power was, wasn't really that clear for quite a while as far as I could tell.
I assumed the “Wolverine” appellation was because he was only 5’3” but willing to fight much bigger opponents, not unlike the animal which is his namesake. I didn’t think it had anything to do with his status as a mutant.
Wolverine’s name falls very much within the original Marvel “style guide”, where Stan and the gang gave us several characters whose names evoked their primary characteristics without actually describing them. Cyclops springs to mind. Quicksilver. Medusa.
It has a lot to do with being able to pick someone out of a group based solely on the name.
(The ANAD X-Men kinda stumbled out of the gate on this one, with Stan famously thinking Storm was Banshee, and Nightcrawler was Wolverine.)
