Hey, don't let me kill your idea. Stick with your Infiltrator if you like and if you put one together before I do I've got another idea to fall back on.
I'll gladly toss my hat in the ring to play a SWd20 game. I haven't played a SW game since the d6 days. Don't worry, I have access and own some of the rulebooks for SWd20. I'll cook something up and toss out an idea once thumb through what I have.
