If I were the head writer of Supernatural, and if I had control over how Season Seven would go/has been going, this is what I would have done. (Originally outlined with
ravenspear and then shared with
_bluebells in a comment, and I want this here for posterity.)

It was something along the lines of the BSG episode 33 - basically Dean and Sam wake up in a hotel after the events of the S6 season finale, and while they try to get their bearings/resume hunting/try to stop Godstiel, every three days they get a phonecall. An anonymous tip about a location, and the first call they blow off, figure it's some nut with their number. Read the news after those three days, violent deaths. All the tell-tale markings of a monster they should kill. Except that there's another call, another location.
They don't ignore this one, and barely get the monster downed before the next call.
And the calls don't stop coming. They don't always make it. All of season seven is them running on coffee, fear and adrenaline, trying to stay ahead of the calls/monsters and when not doing that, trying to find out where the calls are coming from. Who's behind this.
The first time they see if they can't get another hunter to cover a call, that hunter winds up with a broken down car or worse - and a phonecall from their anon, admonishing them not to skip out on their duties. (Though other hunters cleaning up monsters on calls they couldn't get to on time are fine...though that way can't be relied on, because that's always after some innocents die.)
And that's my premise for S7. Tense monster hunting, a return to the meat-and-potatoes hunting we were promised in S6 and didn't really get, and enough of an overall plot (who is behind this, how can we stop it + Godstiel is suspiciously silent, what is going on in Heaven/with him) to please those of us used to that.
Whaddya think?
EDIT: Details could be tampered with. Instead of three days, make it a week. Have more Godstiel in places, doing his Godly thing. You know.
