Except that would be Mistborn+Medallions. The "Shardglasses" are Radiant+nothing.
Spook never had any Atium, the only person to currently have Atium is Marsh, all the rest was burned. Also, some metals are difficult or even impossible to make in those times. The way I see it, there should be three catergories:
1. Mistborn with steel, iron, tin, pewter, zinc, brass, gold, electrum, Atium, bronze, copper, duraluminum, and aluminum. For equipment, they have glass daggers, a coin pouch, and a Mistcloak.
2. Mistborn with all sixteen metals, but no Atium. For equipment, they have aluminum daggers and a coin pouch
3. Mistborn with all metals we have seen in the books, equipped with aluminum daggers and a coin pouch.
This is my opinion on how the fights would go:
1. Radiants below third ideal have no chance unless they are from either the Skybreaker, edgedancer, Windrunner, or Dustbringer, and have the terrain advantage. With Plate, and possibly shardglasses, those orders win most of the time. The other orders have a chance once they get Plate, depending on how powerful living Plate is, they could possibly win.
2. Radiants without Plate lose to chromium unless they are either a Windrunner, Skybreaker, Edgedancer, or Dustbringer, and are in a position were they can use their full mobility, or a Lightweaver who fools the Mistborn with illusions. With Plate I think all the orders would win, unless chromium instantly destroys Shardplate.
3. before Plate, all orders lose. With Plate, only the Windrunners, Skybreakers, Edgedancers, and Dustbringers have a chance, and I think the terrain will decide the victor.
(I didn't include Stonewards because we haven't seen them in action yet)
On a side note, could Lightweavers make a bunch of fake Atium shadows to fool a Mistborn? I know that illusions can be detected by bronze, but it would still be extremely confusing and could help to negate the effects of Atium somewhat.
