Wow this is a huge project. Just one question, why do you need the 
first 16F? I guess the 18F4550 has enough power to handle

They are quite some examples for 18F4550 for LCD/HID function. Check for
Microchip Forum USB section. A guy named "yts" has posted some example
codes.

A guy named Holger Klabunde also has a USB CDC based LCD codes for
18F2550. He has a CrystalFontz Display emulation example and a 
Matrix Orbital Display emulation example. I forgot where I got
his demo codes. Most likely I got it from Microchip Forum as well.
