Change camera settings?

[ArchDome]

I'm hoping to create a First Person Camera mod, but changing the FOV settings for any ZCamera objects doesn't seem to cause any changes. I'm also wondering if its possible to change the camera position as well so I could place it inside 47's head.

As a little proof of concept here's what the game looks like when I fly the free camera into the ideal position.

There are some camera values in the ZDefines:

To attach the camera to 47's head, my first thought is to simply change the scene hierarchy to make 47 the parent of the right ZCAMERA object, and set the ZCAMERA's local position to (0,0,0). However not sure if that even works.
