Is it wrong to wish someone would revert?

No, that is not wrong at all to have love and concern for others so you do not want them to suffer in hell. Of course you should pray Allah might turn their hearts. I will keep you in my prayers, I think others will, and please you keep all of us here in your prayers too. I want to keep all my brothers and sisters, of all the different sects and despite our disagreements, we are all Muslims, to keep you all in my prayers. Salams.
