You have touched on the major Issues I see with this tree now Barefoot but I am not sure I can agree with all your remedies.
Tilting the tree more to the right than it is at the moment will exit the soil at more of an angle and this will also improve the new angle of the apex, but I think it would actually make the base look worse.
I think the front before repotting last spring shows a better base than now. I don't see how tilting it more to the rightwill improve the base. I am planning for some where in between being the best between angling the lower trunk and showing the best nebari.
I am working the base and the apex. Maybe I can tilt further right in the future but I think that will be at least 10-20 years away.
I do like the idea of thread grafts to increase the base flare on the right it has been a constant issue with the tree. There are dormant buds there and although all the other buds shoot out they never do anything. I might muck around with that next year

It's too bad your in such a hurry cause the stories I could tell you, Bushels and baskets of stories, hole crates full of stories. But if you can spare a moment I will tell you one story.
