Possible Chinese Elm Air layer?

was walking by this tree today and I had the thought that because this looks like an old branch that was chopped and caloused over. Wpuld it be possible to air lay this? It would make an insane little sumo Bonsai if it was possible. what does eveyone think?

I'm not 100% sure, but I think the other side of an airlayer needs to have leaves on it

That is correct. There needs to be foliage.
