Holy moly, that's a lot of light!
You should need that much supplemental T5. You should be able to get what you're looking for just by using a Fiji Purple and then either an Actinic or a Blue or Blue Plus.
I used to be a huge T5 advocate, but I'm recently starting to change my tune. I think for the average reef keeper that it is easier to have more colorful and better growing corals using metal halides (with or without supplemental T5s). There are A LOT of factors that contribute to color and growth, and lighting is only one ingredient as I'm sure you know.
