I'm glad that someone is taking this on, and I wish you much success.
T.I.H. is such an under rated film. I think Edward Norton did so much for that film, and it's a real shame (but no shock) that his character input ideas were disregarded and unwelcome by the producers and director. When they have a talented and appropriate actor in the title role, I want to see more character development and a much more talkative script. It's only when you have goof ball glam boys and no talent bombshells in these action films (See any Michael Bay film for an example) that I just want explosions, some naked nipple, a few cheesy one liners, and a plot hole filled quick to the finish ending.
