It would be nice if we had glamours for jobs that made our weapon look different. AST could have crystal balls, WHM/BLM could have wand and shields back, etc etc. We already let PLD tank with their shield hidden so it's not like these little changes are unheard of or game breaking.

A WHM with their wand and shield would look a lot like holy pally (well, more resto shaman but same deal with the mainhand-offhand :P).
