Would you like to play a game?

Ok, so I've been toying around with an idea lately.  I've been thinking of trying to create a bit more interactivity here, giving people who come to my blog more of a chance to participate.  But, rather than just jumping right in and starting, I thought I would ask for opinions first, see if anyone would actually be interested or not.

Here is what I was thinking.  I was going to try and start a little game up.  Essentially, I would post a comic strip or page from a manga.  Only I would remove the dialogue from it.  Then, each of you would submit your own text to fill in the dialogue.  Anything you want to write would be fair game, so long as it was in some way TG related (this is a TG caption blog, after all).  Whichever one is the best (best could be funniest, sexiest, most interesting, etc) would win and get a prize.  Prizes would be things such as getting to star in a caption, or perhaps a custom morph (send a picture of 'yourself' and I'll create an animated morph for you), or something else similar.  I'm open to suggestions on prizes.  I would probably do one every week or possibly every two weeks.

So, for example, I would post something like the image below, and each of you would make a comment with the dialogue you write for it.  In the event that two people have the same idea, whoever posts first would get the credit if it wins.

If I were to start this up, would anyone be interested in playing?  Or would it be better in a different form?  Any thoughts, suggestions, comments, ideas or anything else?  Please, leave me a comment so I know if this is something I should consider pursuing or not.
