A passing thought.

A lot of armor from these games would look absolutely excellent in DS2, even if it's at the same resolution as our favorite '05 game. Ornaments could be used to make unique shoulder pauldrons and things that these armors have. Armors from;
Dragon Age- most armor from all the games

Original DS armor (We're already working on that though, lol.)

Fable: The Lost Chapters and the DLC in the anniversary. (Some of these could actually be made by retexturing armors already in DS2, I'd wager. The Leather armor, besides the daggers on it, for example.)

Assassin's Creed robes might look neat but without a physics engine in DS2 capable of physics In-game (Correct me if I'm wrong) that'd be a pretty monumental task and totally not worth it. xD Of course we could probably make a version without flowy bits. I know Unity has robeless armor.

Monster Hunter armor, of which fits the DS2 world in color scheme, but not so much in the Eastern style. Then again, one could argue that DS2 is missing some Eastern-inspired armors. (I'd bet money that bare_elf would like 'em xD)

ESPECIALLY Dragon's Dogma (and the DLC) and Dark Souls armor, looking more realistic. Both have some Eastern influence as well, but not overly so. Not like it's a bad thing anyway.

Elder Scrolls armors kind of goes without saying.

Even if no one ever actually implements any of these, it's cool to think about.

Another thought from the Dragon Age side of things;
Is it possible to add a sort of active effect on the characters that covers them in blood in DS2? For example, add a 1% chance to get this 'debuff' each time you kill an enemy. Use the magical effect that surrounds the characters to instead splatter them in blood. I imagine there would, however, be a problem with making the blood conform on the body. But it's a neat thought.
