Zombie Ma(p)gyk!

I have decided to sell my soul to GtkRadiant and make a siege map. But I have extremely limited knowledge of radiant (i've poked around with it a little in jk2, but that was yeeeaars ago) and so I have decided to build up to a siege map by making a zombie map first.
Here are a few different choices, and they all sound exactly like what they would be.
Zombie Rooftops: Early on in the SP, there is a level where you jump around on the Nar Shadaa roof tops. Think of this map like that. Very easy to fall to your death, and maybe a few super-distant buildings to demo launch to (I'd have to find a way to make these zombie-accessible) Maybe teleporters between different buildings on the map.
Zombie Stadium: This map would be like a sports arena/Colosseum. Think like Desert arena area, but much bigger and more futuristic and less deserty. You'd be able to run around on the arena floor, in the seats, press/VIP boxes, and underneath the stands would be concession-type areas to run around in.
Zombmusment Park: Zombmusement park would be a an amusement park-themed map, think like Pacific Playland from Zombieland. It would have waterslides and stuff to slide down (one thing I actually do remember how to make from jk2) and triggerable rides like drop towers (would be a freefalling elevator) and rollercoasters (if I could figure out how to make them) - this would also have different areas like a house of mirrors/haunted house, etc.
Zombie Sulon: Possibly the most adventurous suggestion, for those of you who played JK1:DF2 back in the day, you know you go to Sulon - Kyle Katarn's homeworld, and you investigate his Father's house. This level in Jk1 always had a really creepy vibe, what with the old house being run down and stuff. In this map, I would aim to recreate Moran Katarn's farmhouse and the surrounding area.
