I'm afraid not:
Empower Spell:
All variable, numeric effects of an empowered spell are increased by one-half. Saving throws and opposed rolls are not affected, nor are spells without random variables. An empowered spell uses up a spell slot two levels higher than the spell’s actual level.
I beleive in the book, 3.0 or 3.5 it actually uses dispel magic as the example of what you cannot empower.
