It would certainly help... any extra light will help when the tank is

This other person guts the hood and replaces it with two shoplights, or a
canopy that holds 4 to 6 T-8 fluorescent bulbs. Others try VHO
fluorescents, with 3 times the wattage in the same size tube (you'll need
new ballasts for this). Another alternative is the newfangled "power
compact" fluorescents that pack about 2-3 times the wattage into a smaller
package (for instance the perfecto SHOlight hood).
I would say you're on the right track here. But keep in mind there is no
magic "wattage" that will work. The 2-4 figure is just a *starting* point
to give you an idea of what sort of plants you would be able to keep.
