Thanks everyone. I want to also thank all those who shared they're ideas and mods too. Thanks to John for the ears, thanks to Steven for the frown mesh, thank you Stomper for your aerators, and a big thanks to Mike. Mike's "Converting a TE2 into a Hero" tutorial was a great help and was the reason I wanted to try and make my helmet a little better.
Don, I have been debating on doing anything to the inside right now only because I don't own a full armor and won't be trooping any time soon (being unemployed sucks!). But I do want to add stuff to the inside eventually.
