Hi, it's been tried very many times by very many people and the consensus is that it's not a bonsai candidate. It doesn't grow 'properly' for bonsai purposes as the long horizontal branches don't take to wiring well, don't bud back appropriately if cut, and it just won't behave the way it needs to to become a bonsai. I've only ever heard of or seen one example in 25 yrs of being 'into' bonsai, and that was one in a book by Isabelle and Remi Samson years and years ago - and IT was not a typical bonsai by any means, but relied on being wrapped to some extent around a core of itself in some odd way, rather than traditional methods - didn't LOOK like a N.I. 'pine' in the end either.
