To this day she still doesn't technically have one! I spent so long calling her "pilot" as a placeholder name that anything else sounds weird to me now. No proper name certainly makes writing dialogue tougher though.
Maybe you could try adding a comment/forum to Spacethumper 2 to get basically a survey from the audience if there is a name they would prefer? All of the dialogue in the current games would still work since the name is never mentioned but it would probably make writing dialogue easier going forward.
