Retrofit t5s in a 36" canopy?

[needmorecowbell]

I'm looking to put 2 t5 bulbs in a 36" canopy.. I have a led unit in the middle. I'd like two separate fixtures, how could I do this? They are going to be at the front of the canopy and at the back, they don't need to be the 34" bulbs, it could be smaller, I'm using it as supplemental lighting.

A picture of you current hood/set would be very helpful. Depending on the set up different ways could be utilized.
