It could be considered a upgrade. His armour looks a bit flimsier than her shield; he'd be upgrading his armour, making it better and becoming stronger by utilising her shield. No, no, now you're mixing things up. That would be modifying the Shield, Pyrrha's Shield. By "upgrading" I meant upgrading the item in question, not something else with it.

Basically: Upgrading the shield to make it a better shield, it's not a problem, unless the upgrade makes it too aesthetically different. Modifying the shield to make it armor, is more of a problem.
