The question that comes to mind is: Why would you like to do that? Allowing the roll I mean.
I can see sense in having the players explain how they solve a certain issue, and from that derive some generic roll if needed. But otherwise, why the focus on a roll?
(not to be rude or anything, just being curious)
"Anybody got Use Magic Device?"
"I'm not that kind of rogue."
"Anybody got Sense Motive?"
"I'm not that kind of bard."
"Anybody got Knowledge (Nobility and Royalty)?"
"You're kidding, right?"
Also Stream: I dig the dwarf cleric knowledge devotion idea. It'd be nice to find some more skill points to sink though.
