I've been barking up this tree for a while; I play both AST and WHM and I often glamour an outfit to match a (new) weapon and sometimes what looks good on one just doesn't look right on the other. If glamour could be assigned to an entire job/class rather than the gear, this might be some sort of solution.

Asking for more gear not to be designed for cross-class (which I'm willing to bet only future job AFs will have, now that PvP gear shares roles now too) will be reasonably met with stiff opposition about inventory/armory bloat.
