I've always seen ChiO and AChiO using 2 or 3 girls respectively to make their letters with their arms/hands (though I suppose the alpha could look like a lambda...)
Then there's DG - I've seen 2 girls where one's making the delta (like tri-delt) and the other makes a gamma with her thumb and index finger, cute stuff!
