Since it seems that Love is what is to be used to destroy Voldemort in the end, I've thought up one possibility for at least a crackfic.
The only Love powered weapon that seems to be able to do the trick comes from 8-Bit, namely the signiture attack of Black Mage Evilwizardington. The Hadokens main power source is love: every time it is used, it drains a portion of love out of the Universe. It also causes divorce rates to skyrocket. Although it's cost is rather high, he could easily kill some of the Death Eaters and use their kids for the sacrifice.
For a demonstration of its destructive capability look here and then here.
