yeah.. i would just keep it like you have it ... i like the idea of using different spectrums of light as well.. i just put one bloom bulb along with three veg bulbs in my t5 set-up as well... let the plant tell you what it wants and likes.. if it doesn't seem to be happy, ie growing and healthy the way that you have your bulbs, then i would try another placement for the bulbs.. you can take all of the suggestions that you want, but at the end of the day you should let the plant be your guide and listen to what it tells you..
best of luck
o yah.. there are plenty of threads on here just for people who grow with cfl's only.. do a search and i am sure the people on these threads would be more than happy to help you out and with any farther questions that may arise later in your grow.
