a New Type of invitational

Now I've seen this Batman Invitational, and I was kind of wondering if we could expand this concept.

It's still all about the writing, but this time, not about everybody roleplaying the same character. No, this time, it's going to be about each other's characters.

Yesterday afternoon, an idea for a non-canon Krious story slipped into my mind. If I have his permission, I would like to write it out as true to his character as possible. After that, I'd like him to grade the story, giving feedback on what was true to his character and what was not, ending it with the grade to show how close I was.

I don't know if others have this as well, but I'd reckon I would love to write some stories about other characters as well. I'd like to know if you yourself would like to, for once, rp a story or write some fiction about another character. Just for fun and writing.

Yay or nay?
