"Has anyone done a natural spreading to the ground of a cluster? Does anyone know of one? This is the image that’s anti-bonsai that I want to miniaturize. I love live oaks like this!"
i didnt want to clog Markeys threads so answering your question here
you can find trees like this all over. i saw Will baddely attempt this with an English elm, it had a very thick low branch that he purposely broke so it laid flat on the soil, scraped the bottom side of it to encourage it to root, like what happens in nature, here's an example
you can see where some type of trauma has cause this branch to split from the trunk its still live and growing looks a little weak though, probably not the best example

this is an oak tree in the isle of wight called the dragon tree, interesting story behind it
Dragon Tree, Brighstone, Isle of Wight
With its huge snaking boughs, the Dragon Tree of Brighstone is a sight to behold. One massive limb forms a bridge over the Buddle Brook below, which used to power the nearby Brighstone mill until it closed in the 1960s.
It’s thought the oak took its unique shape after it was blown down in a storm, but, still supported by its existing branches, managed to re-root.
Local legend, however, holds that the tree was once a dragon that terrorised the locals. A knight fought the beast. When he struck the fatal blow, the dragon turned to wood.
if you can get hold of a few bits of yamadori, then anything is possible tbh. i think it will be difficult to take certain features from these trees growing from seed though.
