SPN: The future?

echan said something to me about SPN fandom being in a tailspin about the possibility of season 6, my summary of it was as follows:

The Network: This show is high-rating and money-making! Why would we cancel it?
Fandom: WHY GOD WHY.
Kripke: You know the whole apocalypse thing is too big, what if for season 6 we gave them a really simple thru line, you know, as simple as season one and being on a quest to find their dad.
Fandom: ...Oh. Well if you put it like that...

echan then suggested it would be completely hilarious if Ackles and Padalecki refused to play ball, since reportedly they have said OMG IT'S DONE too.

I then suggested Season 6: Castiel and Gabriel on a roadtrip across America to find their father.

I then wondered, if I posted the idea to my droll, would someone write it for me?
