Devil's Advocate, you missed one other obvious thing - teeth. We've mostly got them, and they're all ours and mostly fairly straight following dental assistance. The rich would have their removed and replaced with false one, so they didn't get infected (wasn't Washington famous for his wooden teeth?). So anyone playing an officer, it's tooth extraction time...

Me, I'd rather see the Society for Creative Anachronism go for it. At least there, they recognise that trying to recreate a battle will inevitably fail - for one thing, everyone's got to get up at the end! So if you're not going for total accuracy, you can at least stick to the spirit of it.

Grab.
