Um am I missing something here mate or isn't there already a fair amount of blue on the back?
Inivis, I'm with ford, think no lip is better and the focus on Vin's upper head is a good way to go.
You've probably tried, or don't want to

But, what would it look like if Vin on the back was in color but you keep the blue in the SF area and over the screens?
Agree with V that tag line would be cool
I did mean that the front could use some of the blue from the back.
