We were in Bariloche early December - still cold & very rainy. We hiked up to Refuggio Frey twice (climbed 1 day out of 5 the first time; second time we left the gear in a hostel and did the walking circuit) Had to lug everything in, it's about a 6h walk+ with all the gear. But bloody gorgeous.
It's a bad time of year for walks as well, as all the glaciers are melting so the tracks are flooded.. But what we did see was nice.
You could easily do a week in Bariloche & 2 weeks in Cochamo - I haven't been, but all reports are jaw-dropping. Again, big walk in lugging all your gear... but worth it.
I have a friend who is a much more experienced and confident climber than I who said Cochamo was crazy big wall that was too much for him...
Judging by your posts - I think it's right up your alley.
