I have no trouble dropping the alignments completely. You can pretty much tell the basic Good/Nuetral/Evil stance of the deity by their portfolios and the minimal background information available.

Iridala: Beauty, Birth, Family, Fertility, Healing, Home, Love --> Good

Nymdyl: Divination, Dreams, Fate, Illusion, Sleep, Time --> Nuetral

Vhikuun: Cruelty, Domination, Fear, Greed, Political Corruption, Strife, Tyranny --> Evil

So if we are trying to be system "agnostic", just let me know how you want it represented (if at all) and we'll change it.
