Ah... a pity. Well, that's my primary concern. Having never attended Anime Conji myself, I'm sure you have a better gauge of what the attendees are into and enjoy, but in my experience at other cons there's been an increasing level of grumpiness about non-anime cosplay/events/panels ranging from minor crankiness to serious hostility. I just wonder how your audience would feel about it.
Personally, as an editor, I don't mind one way or the other. I don't particularly have any interest in editing non-anime footage at this time, but the wiggleroom in the rules doesn't hurt. The whole Disney thing does concern me, though.
