Do not give different options to "commercial purpose" and "non-profit
purpose".  It will confuse _everybody_ .

a) Can a non-profit theatre company charge an admission fee for people
to see a performance of your material?
b)  If so, does that usage fall under "Non-profit usage' or "commercial usage"?
c) If their usage is non-profit, can they slap a "BY-NC-SA" licence on
their derivation?

USe one licence.

I don't think that the three you are describing will have the effect
that you want.

And that is the major reason why licences should not contain a clause
allowinderivative material to be distributed under a licence other
than the original one.
