I really like both drafts you have out, particularly the parkour - based one. I think this might be the direction that Kosta and I need to be looking for Eetreia's world. I fear that grafting it into an already very crunchy system like Pathfinder might overload the system, but, on the other hand, there's Spycraft and Fantasycraft that make Pathfinder look rules-light, or that thing Monte Cook did with tokens, so it's probably just me being lazy.
That said, I would kind of like to see a system built around this at its core - I'm pretty sure this is *exactly* what Kosta had in mind.
