If you can't make it to Peru and Bolivia spend the extra time in Colombia and Venezuela. Colombia is some of the best of everything of all of South America
and the Andes in Venezuela aren't half bad
, I got over 14K feet the other day and it's the cheapest gas in the world, really helps pad the old budget before getting into the super expensive Brazilian fuel
I've been quoted 5 days for my Brazilian visa in Caracas and 10 days in Bogota, I think I'll spend my time waiting in Colombia if I don't have a passport.
