I don't know if this has been brought up already. We have eye-patches and sunglasses for totems , what about a hook for a hand or peg-legs?

the hooks can replace one hand only allowing you to use one handed weapons such as pistols and one handed swords etc. maybe the hook can have an epic looking power or attack with it. maybe also have class spasific hand replacements that are daggers for swashbucklers or pistols for musketeers etc.

the peg-legs May be more complicated for KI cause it would involve changing how out characters move. they would have to hobble around to look realistic it may be funny. If these did exsist maybe these can have different looks from each world. A normal peg leg from SI. A totem pole like leg from CR. or a completely working clockwork leg from MB may be they can also have a cool power like Rat Beard does with his wooden leg.
