Both of my horses are ex-jumpers because of stiffness but they ad still enjoy it ^^(I know because they would rather go for a jump then stay to the sides for the arena and caught me by surprise

) i think any horse could learn it easily. And any horse can be a project pony just depends on what they know and what you want them to know I have to teach Pasqual and Turtle neck reining get them used to western saddle and possible teach Turtle dressage but when its basic English and jumping I dont think they have much to learn. So it just depends they dont have to be labeled project pony just you want to teach them something
