Great Job DimeBagHo, after some historical research I found another quick change that you might want to do:

Roman Velites shoud be similar to heavy peltast in stats and use square formation.
It seems that before the reforms Velites were supposed not only to do the usual screening job but also to actively engage the enemy skirmishers to clear the path for the legion... This was their way to compensate for the lackuster quality of their cavalry.

Anyways, if you want to focus on the important things I might help you by releasing a "foreigner macedonian style warfare edition" with your permission, so players that wants some extra depth for the punics and the like can get some quick and dirty add-on...
