People run roleplays like this all the time. There are game masters (like ye olde Brovo, who left RPG some time ago) that use a stat system in every roleplay they run. The system depends on the fact that the consequences of the characters' actions aren't left up to the players -- they write their intentions in their posts, and after a round of posting, the game master responds with the results. Sounds familiar? It's very D&D-esque. Brovo even rolls dices to determine the outcomes.

Yeah, that's kind of what I was thinking. I decided to make an interest check for it with more information earlier, so if enough people are interested, I'll develop it to a playable level.
