The watts isn't determined by the rating on the bulb, it's
determined by the interaction of the bulb and ballast. The
rating that's given for a fluorescent bulb is based on a
certain kind of ballast. If you change the ballast, then
the rating doesn't necessarily apply.

Whether they will light, stay lit, and not burn too cold or
too hot to give acceptable output and longevitiy is hard to
say without trying it. You can try diff combinations and
see what works acceptably. You might try instead to find
some magnetic ballasts designed for 20 watt 24" fluorescent
T12s. They should only costs a few bucks. These often are
rated for 15-18-20 watt fluorescents. You can probably find
them at Home Depot or any supply house that sells lighting
