an arena banjo tooie map that's based off of an existing fps segment/map would be great. the aztec temple, or glitter gulch mines would be neat to play with/in tf2, if the work wouldn't be too hard. not sure how it would translate to tf2, though.
I hadn't thought of spiral mountain, but wouldn't that kinda make everyone pushing leetle kart into sniper-bait? pl_bob-omb would be cool to see, though, if the mountain was the last point or something (pushing from red bob-omb cannons, or something, don't know what you had in mind)
I HATE ctf. such a cluster *censored.3.0*/stalemate in the base, once everything is set up.
if you do a joke/sandbox map, I think an animal crossing village would be fitting, if you felt like it/had anything you could do, design-wise.
anything is better than what I'd do.
