These 10mm miniatures might 'coincidentally' be very useful for you!
http://www.copplestonecastings.co.uk/li ... t=6&page=1Look at those patterns on the shields! Remind you of something..?
I bought some of these a few years ago, and I really like them. I have not yet played a game with them, but I intend to use 2 infantrymen on a 15mm base as Army Markers for a Map Campaign.
As for using them in WotR, I think it would work very well. Just scale down the bases and all ranges with a factor that you think is convenient, and there you go! It will be much easier to manage these armies. Only think that you will need to add, is dice to indicate casualties.
Or, what you could do, is represent 1 infantry company by 8 of those stands (arranged 2x4)! That way, the base size might be very similar actually, but now the armies would look much more massive and overwhelming!
