Looks like you could order a few kinds of crabapples and plant them as rootstocks from Coldstream Farm for fall (October-November) delivery http://www.coldstreamfarm.net/c-36-crabapple.aspx
I'll probably just wait until the spring!
I've got one that I grew from seed, so that might end up in the ground pretty soon. We'll see!You could try rooting some crab apple cuttings. But I do not think you'd be any father ahead than ordering rootstock for March.
