The bulb I've really been liking is KZ's New Generation (14.4k), so I'd say get one of those. As well having a KZ Coral light 10K would look good. You already have a KZ Fuji Purple which will compliment the other bulbs. I would say getting a Ati blue +, or a Ati actinic blue if you can not find the blue + in the mix would be good (does not have to be ATI brand).
I've been running a 4 bulb 48 inch tek unit in my 125ish gallon tank with the following config and am liking the overall lighting look and growth in the tank (after trying may different bulb configs).

Front bulb- ATI Superbrite (similar to the GE 6500K)
Front middle- ATI Blue +
Back middle- KZ Fuji Purple
Back bulb- KZ New Generation

As I have it the middle bulbs turn on a 1/2 a hour earlier and later then the front and back ones. So with a similar ratio in your eight bulb unit I think you will be more then happy with the results
