I liked the depiction of Gondor in Peter Jackson's Lord of the Rings films. I'd like to see Aquilonian knights depicted similarly as in the films. I love the high crested helms but I'd make the armor a little less ornate, give it a plume and a surcoat with Aquilonian heraldry or black for the Black Dragons.
I think I could find some 15mm minis that would be converted with a small amount of fuss. If anybody has any ideas of minis that would fit the bill, I'm open to suggestions.
