Im not sure about making every GP upgradable to a hero. This makes the flavour heros kind of useless, as you are capable of building more powerful heros by upgrading these to tier4 units.
I would like heros to be something more special, granting only 1 to 4 to each player over the course of a game. I would prefer that every time you get a GP there is the chance to create a fitting hero insted. (I would still prefer that this is the way the flavour heroes are built too)
EDIT: this could of course be combined with Lightzys/woodelfs idea giving smaller civs a greater chance to acquire a hero in times of need.
