I think he sounds good for you. If you are mainly doing local shows just for fun, I think you guys could grow together :) I have seen Draft/TB crosses run barrels and place! Also I VA I knew a Morgan/Percheron cross the could jump fences like a dream one day and pole bend the nest. Drafts CAN be versatile, you just need to take the time to train and condition them.
My freind has a draft and he can't bend his neck because he was used by the omish to pull carts and he had that big collar on him so he could only bend his neck about 2 inches at most.and he is super slow.i would go for a draft/quarter horse cross they are usually pretty big and some of them are great for dressgae.
