MSQ dungeon

I found Beatrice's castle interesting in the MSQ dungeon. Obviously she is Beatrix from FF9, her portrait even looks like the FF9 character to a T. I never finished FF9 so I wonder if anyone has a take on the paintings in the Castle during the MSQ? All the women seem to have had their faces scrubbed out and only the men remain except the one who looks like a Caster or Ninja. You don't normally see details like this without it being an easter egg/clue/red herring.
