Wow, that is awesome! I love it. You have to post lots of pictures so I live vicariously through you. :p
I like oblivion twisters idea. the lights on the bags look awesome, defiantly the right style, and then using the third would be great for a break light. Do you have a color in mind? I think that will influence leaving them red, or going clear.
Have you thought about pipes? I have a set of Harley touring pipes that might look good on your bike. I haven't decided if they look good on my bike yet, but I am leaning toward selling them and getting a different set.
