Double ring CCFL Angel Eyes FL headlights

So, I had a thought after seeing a RED CCFL AE FL lights on a tibby and liked the look..


So would it be possible to do two sets of ring per light?

One ring white for legality
One ring red for fun

so 4 White ccfls + 4 red ccfls = 8 ccfls..

Thought would be ring in ring outer would be white inner red

Curious as to the sizes for FL headlights as I have the ugly bubble lights atm and what size would fit inside the larger one?
