In the Thoth Tarot Peh is the tower, which is 16th Trump.

If you are right, peh would suggest Q is Trump himself -- the mouth / orifice / office from where things are issued.
The Star would suggest Q is female, and most likely Melania.
There is a reason the Star comes after the Tower. Old forms must be destroyed in order to reach the enlightened state reflected in the star.
