At most I've only past through Arisaig on the way to Skye (in hindsight we probably should've stayed in Arisaig), but I read a beautiful article in Scots (Heritage) magazine regarding the Ardnamurchan peninsula, so you might look into that? I love Fall & Winter, so with the snow and all it would be an exciting trip for me personally. That's about all the cents I have to give unfortunately...

Slainte,
