Imperial Masterpiece
This is a signal example of what happens when a tree is never pruned for compactness over many, many years. It has gotten to the point of no redemption. Each leaf contributes to the growth of the whole plant below that leaf (between the leaf and the roots). When the leaves are distributed equally along the trunk(s) there is little contribution to taper. Taper is achieved by having relatively fewer and fewer leaves further and further up the trunk. So, now you're left with a long sausage with leaves.
I would go back to ground zero. Disassemble the whole thing and recombobulate the roots so they don't travel sideways a long distance. That's the first incongruity that grabs the attention. Don't necessary remove the rock from its position, if you can, just free the two long sideways roots, rotate the rock so those roots point as vertically as possible, and replant. You will have a sausage pointing up and a companion cascade sausage. Then, reconsider how much of what will be the top to remove. I like cascades that have a strong counterbalance which you have the makings of, here. There is one big utility of long branches: you can wire them to make substantial movement. You can't do that with short branches. You will have lots and lots of castoff pieces, so you could grow a whole separate forest. I'm partial to forests. And figs.
