I thought of a new experiment for you (although it wouldn't surprise me if you're already trying this). Using a disease resistant rootstock, graft on a dwarf variety, and then, once that's large enough, add on your other cultivars....
Sounds like fun - lets do it. Should be easy enough. I have some seeds of Mountain Merit & Amelia i can try out. I do have a Dwarf that survived our freezing temps that i took a cutting from to duplicate the plant as it seemed to survive almost a week in to the 20's without any protection/covering. Most likely due to the micro climates around the house.
With all the varieties i am growing right now i can easily harvest scions to do a multi grafted version that is disease tolerant.
