Praise the modders
Modder Zulliethewitch has made mods for both Dark Souls and Dark Souls II that allow you to play the game in a first-person point of view (like From Software’s original King’s Field) and now the cycle is complete with Dark Souls 3: First Person Mode.
There’s some weirdness inherent to forcing a third-person game into the first-person view, like the floating hands that look like they’re ripped out of a PlayStation Move/VR game, but otherwise it looks like it works pretty well. Of course you’ll want to back data up in case things go screwy.
