On topic however. Once the theme has been revealed, I shall try to create a cool concept that'd work well with the theme so Stage Fever can be revived :).
The majority of the work is independent of the topic of the con. If you're serious about this, I'm sure we can give you some hints and experiences. Though most of the work is finding good skits which equals to motivating fursuiters to come up with ideas (optional, you can outsource this to others/yourself - but needs to be done :), and perform it on stage, including a rehearsal slot. The skits should be funny to watch, and the performers actually be present when the show comes along. You might need some stagehands, too, but this is more easily solveable. A story arc would also be nice, but presents additional needs for story and performers.
So this is not only having one person hosting the show, but first finding performers and skits, later cat-herding them to actually do the skits, and overall make it an enjoyable experience for both the performers but especially also for the (many more) watchers of the show.
