Well my suggestion is probably going to be quite unpopular around here but since we're a bunch of lovable clowns the worst I'll probably get is a whoopie cushion attack... I think I can handle that!
I would go without a nose of any kind other than your own. Just paint your nose red. No chance of a kid pulling that off! (We hope.) It's also in keeping with a style of clowning that has a more natural look to it.
I can't remember where this was suggested or what this more natural type of clown is called. I think I read it in Creative Clowning but it has been a while.
