I'm not diggin' it. The part I would want for a bonsai is straight and taperless.
But, if I had ambitions of gathering yamadori in the future, it might serve well as practice - you never quite know how to do it, until you have. Right now is not the best time for it - I would wait until sometime after the summer solstice, say August. I would want to harvest the shortest possible tree, but one with some foliage (this is what will power regrowing roots. If it should survive I would let it grow next season (2019) and look to chop the trunk at the end of the 2019 season or 'as buds swell' in the spring of 2020 and start a bonsai adventure! Who knows, you may develp a killer bonsai from it in one or two decades. At worst, you learn something about gathering yamadori (i.e., really cannot loose).
