If you want it to look good hanging above your tank, it'd be pretty hard to do IMO. Since you're planning to retrofit something, you're gonna need a fixture housing for it to look half decent...that, or some awesome wood/metal skills.
How big is your tank? 55 gallons? 2x55W PC will give you ~2 WPG which is decent lighting. Why are you trying to retro another strip light in there?
