Peeta and Katniss? Really? You can't even make up your own person? I don't mean to be rude or anything I just think you should be a little more open minded. Of course you can do it if you want I just like it better if you didn't.
You know it is kind of rude to go straight up and ask them. Some people have they're standards, and as you know, Creativity isn't a easy thing. So... Please choose your words carefully, I suggest you don't well... Yeah, You get what I mean. BESIDES, You could've private Messaged them, Or kept your thoughts to yourself. Not to be rude, But yeah. Maybe it is better. Maybe they have a plot that they can keep and not break in the middle of the roleplay.
