I'm very interested too, so please ignore the haters and keep us informed on this project.

I think making 2 or 3 shorter plates instead of one long piece would help in a lot of ways. By covering separate components, you wouldn't have to remove the whole thing to service the transfer case, tranny, or oil pan. The gaps would allow more ventilation and reduce total weight. Easier installation & removal too. (The 2' x 2' aluminum plates under my Blazer were already a beotch to remove.)

For the oil filter, you could make a hinged door in the front skidplate, like the plate on my old Blazer ZR2. Worked great and a turnscrew latch kept it shut.
