One thing I've always wished others could see instantly, is you hauling corpses.
I imagine if the appearance of the corpse model could be made into the doll you can actually hold.
Nevermind, further I'd suggest it made a 2-handed holdable that increases strength.
Many times corpses entirely encumber whoever would carry them.
But why not give a boon if the person is for instance giving up the ability to hold a shield or weapon,
so that they can carry their fallen comrades. Perhaps even add arcane spell-failure so simulate occupied hands.
Not sure how possible this is, but I thought of just throwing it out there.
