I think there should be some extra thought put into this... and what the IDEAL TYPE would actually look like.
There is a stereotype here, and what some people call "Arabian type" does not always mean the mini looks like and Arabian to others, and what you say "draft type" does not necessarily mean it looks like a draft to me.
I AM A DRAFT HORSE PERSON. I love draft horses. I work with registered draft horses (Clydesdale, Shire, Belgian, Percheron, Spotted, etc.) full-time, five days a week. They are magnificent, gorgeous animals... powerful and beautiful. I make a point to go to the fair specifically to watch them show.
Are we talking Amish-plow-horse drafts, or Show-type drafts?
Just so you know, today's draft horses that are winning in halter look like this:
(Images from Windermere Farm Percherons, their beautiful stallions)
They have long, refined legs, can break level at the trot, have very upright necks. Is this what you want your little minis to look like?
Or, are we going for "farm style" draft horses? Because these are working horses that are not shown in halter. They are very tractable, have good work ethics. But they are not show horses, not shown in halter.
So when we have a horse show, it is to SHOW fancy horses. Working horses are for working. I don't know, that's my philosophy. If I had a chunky Amish-style horse, I would show it in showmanship, obstacle driving... those things which it will excel at. There are classes for EVERY horse, I guarantee you... I'm just not sure we need to make more.
In the Shetlands, take a look at the Foundation classes they have. Those ponies do NOT look like the European shetlands. They still are pretty, upright, refined show horses.
Just my point of view, food for thought.
I LOVE DRAFT HORSES... and I think that there are stereotypes that draft horses are chunky, have more body-to-leg, thick lowset necks, and are mellow.
