I saw this and I have to share it. I may post it, too, on my Facebook.
This horse, Landgraf 1, is a Holsteiner. He is 5/8 Thoroughbred and appeared 24 times in the pedigree of 19 jumpers at the 2012 London Olympics including three in the top 11.
I show him to you here because he looks like a Morgan to me! Some of the old magnificent Morgan stallions look just like this. Check out the video.
My point is that Morgan breeders can do this – they have done this.
