How about Spidean Mialach/Gleouriach? The stalkers paths really are quite good, though I'd want to do these on a good day.
I see there is a route guide here:
http://www.walkhighlands.co.uk/fortwill ... lach.shtmlI did them in winter and one of our party forgot their boots, so only had trainers. She decided to "see how far she could get", which turned out to be both Munros, as it wasn't too icy. She did have an ice-axe though. And slightly chilled feet.
(We did the route the other way around, and came down more directly to the road rather than crossing the Allt a' Mheil)
