Heraldic armors are not neccesary for all lords. Polish lords mostly use lamellar, scale or mail hauberk and heraldry symbol was only on the shield. Teutonic lords use Order symbols, and Lithuanian have practically no heraldry yet. HRE and Bohemian lords use classical western heraldry shields, surcoat, horse etc. If we use all existing armors, shields etc., than you need create + - 5 new surcoat for HRE, Bohemia, Hungary and some shields for Poland. That will be enough. We still need much more light and medium armors, not heraldic, just red-white, blue-white, yellow-black combination etc...
