Hi did you progress any further with this? I'm hoping to do similar ,and don't want to get wrong heads.
I took a break, but I'll give you the gist of the plans/project.
In my fantasy world, set in the Dark Ages, elves are either inhabitants of the world and are progressing at a more advanced rate in terms of developing arms and armor etc or they are foreigners to the world
. Thus, while most humans and dwarves wear chain byrnies, helmets and shields, Elven warriors wear full suits of lightweight chainmail.
I managed to get some unhelmeted heads that work from WhiteKnight? I think those were the last of his stock. I was originally planning on getting Warlord games or Victrix Republican romans and use those heads for the elves ( sculpt long hair etc), and the bodies I could use for orcs.
But then Victrix came out with Alexander Successor's, and I love the style of those helmets. We'll see if those work with the FF bodies, but then, I'd be wasting the Macedonian pikeman bodies.
In a perfect world, red box games would make an army range of elves in their style. I've suggested it to Tre Manor several times, but he seems focused on his barbarians and orcs

NO ONE makes a good, "modern" line of elves that aren't skirted)
I have thought as an alternatee, rather than do all that work, would be to just use LOTR elves, using the elves as travllers through time and space theory. But then I'm back to skirted elves.
If only GW had made the Wood Elves from the Hobbit BOFA in plastic....
Another advantage of using the fireforge figures is that they have lots of cloth on the models. I envision elves as being the opposite of LOTR/Hobbit's depiction..they would not operate in precise units with order and professionalism. Elves IMHO would train in the martial arts, but their military would be made up of individual warriors grouped together, but only with rudimentary training in unit tactics. Each would be proficient in bow, sword and spear. Cavalry would be very rare, as elves would not have the resources, time or space to breed large herds for war. Each elf, as a warrior, I'd paint much like a samurai, with colorful designs and bright, silky cloth, all individualistic. My inspiration for elves is both LOTR and Michael Moorcock's Corum series, where elves live in small clans that rarely see each other for hundreds of years.
If only Tre Manor would do an elf wargaming army....
