Not stupid at all. I think, but you need to measure, that you will find sized 9mm cases will be 0.005” undersized before expanding.

Expanders, can be cut 0.001-0.003” with sand paper and something to rotate it.
I must be fundamentally misunderstanding what the OP has written. I read he used a case mouth expander--which I take to mean flaring the mouth just enough to get the bullet seating going.
