I will add a list to this but this is a good start

I agree with the stacking but I suggest doing even numbers.2,4,6. I say even because you should pan your vocals even. 1 ch 90% to the left 2 ch 90% to the right 3 ch 75% to the left 4 ch 75% to the right. This will make you chorus sound more full, wide and thick.
