Yes you do seem to be packing an awful lot in with that itinerary.
As you seem to be planning future visits I don't see the need to go out of your way to visit Bariloche so I would leave that for another visit and stick to seeing BA, Iguazu and the Salta area in a more relaxed manner.
The Bariloche area is beautiful and deserves a week on its own especially if you like doing a bit of hiking.....it's very relaxing countryside to be in. However if you're prepared to pay the price for air tickets there and back it's up to you.
