Nevermind, I got it to work! Here's roughly what I did:
Made a scene with just the Level 1 Game Object in it +all the children (made it a prefab, see why below), Had the start state of the parent call Get Owner to a global variable called "Level 1"
In my Game Scene, I call this level by doing a Level Load Num Action, with additive. When I'm ready to destroy it, I Destroy Game Object and call the global variable "Level 1"
I also have a third scene called Level Editor, this is where I have all of the Level Game Objects loaded up, and I edit my levels there (because I really want to make my Level scenes devoid of any cameras or anything). Since I have each Level Game Object as a prefab, I can just update them in my Level Editor scene and they update automatically in my Game Scene.
Quite. Freaking. Cool.
Cool enough to distract me from PAX East
