The 54 watt t-5's are only 46.5 inches long. They would fit perfectly in your canopy. This way, you wouldn't need to stagger them. I think the difference in price would be only like $5-10.

You could put 2 (or 3) 2-bulb retrofits in there and have 2 (or 3) different ballasts and plugs to let the actinics come on earlier and stay on later (dawn/dusk).
