TGE modifications to TSE

I recently got TSE and am still reading about what it can do for my project and the new things I have to learn how to make and have one quick question. I know it is kind of vague... but treat me like a moron if you must ;).

I made some modifications to the camera code from examples like Advanced Camera and GodView resourses and was wondering how many of resourses involving things like camera control and crosshairs would still be plausible to use to modify the TSE code. I know TSE isn't ready for me to use as my stable tree for my game, but I just wanted to know what I would be up against now and also when it becomes the final release.

Thanks!
