Yes. There is probably more than one way "to skin a cat".
When I realized that I was going to lose my tall Adenium a few years ago, that after several attempts of removing rot from the major root/caudex, I figured I had nothing to lose and I simply cut several branches off and tossed the rest. Those pieces spend the Summer in a pot with water and were ignored. I took a look at them in September and realized they had all rooted. I potted all of them together into a large claypot.
They are all alive and growing, several years later. I was thinking, and that is maybe really crazy, once the branches are fat enough they are really crowding each other out, I might perhaps injure the Cambium/ outer layer a bit and see if they attach to each other and grow as one. Perhaps next Summer.
