While it would make the whole story-writing bit more interesting, there are some factors that need to be checked off:
1) The other club would have to be in the exact same timeline we are
2) We would have to work incredibly close with them in order to keep coordination.
3) We would have to have some kind of "one person posts this time of day, the other this time of day, etc." in order to keep posts from contradicting each other.
4) Members in both sides of the club would probably have to be willing to write and keep track of a story (and all its posts) for approximately a month or more (which can be tedius).
5) We'd have to actually find a club that writes more than it games.
6) Their writing-RP would have to be precisely the same as ours: taking command of individual characters for writing/character development.
7) They'd have to understand that they wouldn't be able to play "famous characters".
There's more than what's on this list, but it's just to give you an idea of what would be done before launching a campaign of this magnitude.
