You know, I never read, or heard Nick Lenz say he was doing anything "new", yet he was the most original, creative mind in bonsai I ever met. He did what he wanted, you could like it or not, and he did not give a damn if you liked it or not. But Nick had the modesty to not claim to be creating a "new style". I don't see a need to rush out a declare there to be a "Nick Lenz Style", maybe Bonzo Bonsai.
Style is not that important except for judging "Formal Upright" is the style with the most "rigid" rules, and distinguishing between "Semi-Cascade" and "Full Cascade". Most everything else is just debating Art History.
I still have no clue how you can define "Cosmic" bonsai, since we have not to this date discovered any life beyond that on planet Earth. No judge could know what an alien tree would look like because nobody has seen an alien tree. It is just bologna. The only reference for "tree" we have are trees we have here on Earth. The Japanese pretty well covered them, heck, Nick Lenz could work with their system.
Enjoy these photos from the 2019 retrospective Nick Lenz show at the National Bonsai and Penjing Museum. I think these photos were originally from RockM or one of the other Fellow BNUTS here, Point is, this is how creative Nick Lenz was, and he felt no urge to "name a new style". He did what he wanted to, and we were free to enjoy his creations, without labels, names and styles and rules getting in the way.

Oh, Nick did name some of his bonsai, for example Penelope was "waiting for her man", and the Thuja was called the "Demon Cedar" he had a larch forest with rusting tanks that he named after a French WW2 forest Battlefield. His creations truly were sculptures. And like many sculptures, they can have poetic names to clarify their message intent, if they had a message. Some had no particular message.
