Congratulations on your new acquisition. Do you plan on putting it in the ground or keeping it in the pot? Either way it seems to me, amateur that I am, that you've got more top growth than your roots can support. I'm sure you had to cut some roots while digging and repotting. If it was me, I'd cut the tree way back and try rooting the cuttings. I don't know what zone you're in, but you'd have to baby the new trees over the winter.
The thought also occurred to me that if you like the idea of a big potted tree and didn't want to cut too much off you might need a bigger pot.
Good luck and keep us posted.
