Starting them in water is the most common method. If your log root can be fitted with the proper soil for the plant with a pH range between 5.6 to 6.5, and if the plant has good drainage it would probably work. I would expect the root to provide everything the plant needs, but to serve as a vessel for a well-nourished plant with the proper amount of light, I don't see a problem.
