A bear skin cloak would be sick. Specifically the bloody one that Jon the trapper wears. Also some fringed shirts and pants. And maybe some misc. items that do nothing but look cool. Like a powder horn you could buy from the general store or a belt with fox pelts you could buy from the trapper.
Do you know why we don't have any of that? It's because of money. They don't give two shits about story mode, unless it's patching glitches.
Jon my beloved.
