Basically I tried to get greedy. I picked the best large curvy branch (@3-4") in the tree. It had about 8 feet of branch above the layer I didn't reduce. Peeled the bark, wrapped in moss and DE then a plastic container cut to fit. The branch was horizontal and roots only developed in the bottom half of the container.
Once separated I had an 8ft tree in a Tupperware bowl. I didn't chop back the top and stuck it in a pond basket. Not secured well enough a storm blew it over damaging the roots and it declined fast.
Poor aftercare on my part.
