I got an idea from seeing a tree that had fallen over in a stream on my campus's Bio Trail. Raft style generally keeps the roots below the soil or like a normal nebari, what if the root mass was allowed to protrude high above the rim of the pot, maybe even above the highest part of the main trunk. Also, instead of treating each of the branches as a separate trunk, the old trunk would still be the main one. I'm thinking of something between a windswept and a raft style, with the main difference between them both being about half of the root mass above the soil, and essentially not functional. This happens in nature when a tree blows over, much of the roots are exposed and essentially die, yet the tree continues to grow. Personally I don't have the experience to try something like this, but I was wondering if anyone had tried anything like this, or had any pictures of something like this.
Something like this.
