Is it possible to ceramic tile over a standard shower pan if it is modified?

Cover with cement board?

Just trying to think outside of the box:)

I Don't See Why Not, You'll Have To Remove The Drail And Find A Way To Seal It Up Again, To Me That's The Only Catch, Id Also Be Curious To How The Floor Gives, Usually The Fiberglass Floor Have Some Give To Them, If You Add Tile It May Crack On Ya,
