I would prefer if national championships were raced by regional teams (counties, states, provinces... or whatever). It would be fairer as well as educationally beneficial for foreign viewers.
If nothing else, we need Froome at the tour for his mountain rescue skills

The population of Slovenia is approximately equal to the population of the 20 arrondissements of Paris. Maybe Paris and Slovenia should have a population exchange.
A Froome-Contador rematch as part of the pro peloton would be anticlimactic, unless it's a handicap race. Maybe a 1v1 200km race on a flat motorway with no wind would be more interesting
