Okay this may be a little late in the game to help but I've gone to anime dating games at both Kumori and Sakura con and even been selected as a contestant on the answering questions side and my sister has been the one picking the date before...
The host I think sometimes makes the game because they get to throw in their comments as they see fit, keep the program interesting if the contestants are boring or keep some more naughty ones in check. They have the power of the mic and all their comments being heard.
I like to have a lot of laughs from watching the games some from getting an inside joke, to a slightly naughty innuendo up to being almost embarrassed for those up there! Some of the most fun is the banters that happen with the host and contestants.
I think a dating game panel works best when the one choosing knows the questions but the ones answering may not know. Also the bigger the variety of personas for the person to choose from makes it a lot more fun. I hate games where it's a bunch of people trying to make the most dirty joke and that's it. Also the best choosers are the ones that add in a reply after the contestant answers the question. If the questions are answered by all contestants switching where you start from each time works well.
I have read and loove Girl Genius and think that keeping some questions in the world of GG like "what kind of destructive weapon would you make to win my heart?" should still be in the plans of this game. Maybe one way to bring anime in is making one contestant completely out of their world. Throw in some anime character who would wonder why in the hell this person would want a weapon as a token of love. You could also have some questions be anime related. I hope some of this was helpful to you.
My friends and I are cosplaying: Lucrezia, Oggie, Dimo, and a thirteen year old Agatha. If you would like our assistance in your game we would be more than happy to get involved! Can't wait to see it!
