I dunno how blue/bright your hamiltons are but this should have a ton of pop. I'm think the halides will heavily over power the t5's so maybe the following?
one ati purple plus (more purple + red)
one KZ Figi Purple (more pink + red)
one GE 6500K - warm bulb for yellows and greens - dirt cheap too
one ati blue plus
possibly switch over to the 14k Phoenix once the hamiltons are done?
