looks good. I'd recommend some solid skirmisher/ambushy archers to represent a regional basque unit, who were known to occupy hills and rain arrows down on enemies. And of course, the famed Almughavars as mercenaries would be great. They were lightly armored, employed throwing weapons, and I believe a hacking short sword.
The "throw on charge" ability would probably make sense in their context, as well as some kind of anti-cavalry ability, as they were famed for their ability to avoid a lance and gut a horse from under the rider. Light Almughavar skirmisher cavalry would also, I think, be appropriate.
