I'll address my thoughts to some of your ideas
1. This is fine by us if you do not banner/decal the map with Nazi etc images, and that the map doesn't promote it
2. This is an interesting one and would have to be an extremely hard/long secret that cannot be done often
3. Could you elaborate on 'escape'?
4. That's pretty cool, you could look at Downview's castle wars for something similarish
5. Nice, in fact, Supermax has a very similar game, where Ts must control go-karts from a distance and race them around a track
