In my experience neither stock horses or quarter horses are bred to excel purely at an English discipline. Purpose bred horses get expensive and most people would prefer to put money into something with more proven breeding and a good line, such as some sort of warmblood.
The horse would probably be good enough, I've seen crosses that work out well but most of the time they will not get to higher levels. They are good at the amateur sort of stuff - but so are most TBs etc, which are much cheaper.
While the cross wouldn't be bad you'd be better of with a type 1 ASH or QH, not a mix of the two. At least you could do breed shows, they could be fully registered and if they're a mare breed youngstock.
I like both ASH and QH, they're some of my favourite breeds, and to muck around on and do low-mid level stuff they're wonderful, probably almost better than anything else. Can do a bit of everything, they're sound and have nice temperaments. If I wanted to excel at dressage or showjumping I wouldn't buy either. Eventing I would consider a purpose bred ASH with lovely movement, wonderful temp etc, but I wouldn't want a QH, or a QH cross.
Why are you asking?
