Dark Souls modder Zullie the Witch has figured out a way to swap out the playable character with NPC models.

Zullie has also found a way to equip the fluted armour (from Demon's Souls).

Unfortunately there doesn't seem to be a way to get this mod for yourself at this stage, but you can check out these as well as some more modding by Zullie on their Twitter page or YouTube channel.

Thanks (unofficial) Bloodborne for retweeting it.
