Over 50 posts in I thought I'd toss in my opinion.
First - this tree has excellent nebari and first section of trunk - if it were my tree, I would be satisfied with it as is, at least concerning the basic building blocks, you will always find things to refine, but the "bones" are in place for the first section.
Paradox, I assume you want a tree that will look "pretty okay" in say maybe 5 years or less. Otherwise why spend what you did? In which case - trunk chops and air layer will not meet this time line. So options one & 2 proposed by Brian are good ideas.
If it were my tree (this means to my tastes) I would go with Brian's option #2 he outlined in post #55. Good eye Brian. This plan can create a nice, quiet, serene tree fairly quickly.
I would not be too worried about the bulges on the trunk, yes you need to begin addressing them now, but they can be fixed, good enough for local shows or club meetings, within a 5 year time line.
The first photo in the OP, is the one I would pick for a front, if seeing it in "real world" did reveal anything the photo didn't capture. That given, I would eliminate all the bar branching right away. One my tree, I would keep one of the lower branches for the time being. You can get rid of it later if you want to expose more of the trunk later. At each point where you remove a bar branch there will be a tendency for buds to break around the callus, once the callus begins to form. If you are lucky, buds will break at the top and bottom of the callus, which you would let grow out a bit, to help heal the wound, and since they are no longer in line with the opposite branch, if needed they can become new branches. But if it were my tree I would initially just plan on using the existing branches as BVF outlined in post #55.
Sacrifice branches allowed to run for a couple years at several levels of the tree would also help, but basically, you got the framework that if it were mine could be made into a "pretty okay" tree in fairly short amount of time.
Making a wild, exciting, radically different masterpiece from this tree would require starting over and spending more than 20 years rebuilding from scratch and refining. I would go with the "pretty okay" plan, and maybe pick up a second trident, to do the "radical" stuff with, with a long time line in mind. I know you like a more naturalistic design, but that was not how this tree was trained before you got it. You could do a second tree in the naturalistic design, starting with younger material, and train it that way from the start.
Here is how I see it. Regardless of what someone spent on a tree, that money is already gone, so there is no point in referring to the cost. In business, that is called a "sunk cost" where the money is already spent. For example, in retail, the owner buys a shirt for $10. For him to make a profit on that shirt, he must sell it for more than $10. But as it sits on the shelf, it is worth $0. Many people are reluctant to sell that shirt for less than $10 because they feel like it's worth at least what they paid. But what they paid is irrelevant, establishing cash flow is relevant.
How does that relate of bonsai? If you buy a tree for $200 that tree might be worth $5 or it can be worth $1000. Regardless of the worth, you've already spent that money, you have to determine what the best route for the tree may be. To say, because I spent X dollars on a tree, I must accept what it looks like, will lead to a collection of very mediocre trees.
The benefit of Paradox's tree being a trident is, they grow fast and are easy to fix. Reverse taper can easily be fixed through carving or air layering or chopping. I am certain it won't take 20 years to develop the tree because the tree isn't that large.
If he chooses to air layer, it will take 1 year to get the new roots to take, one year to let the roots get strong. Then chop off all of the branches, one year to let them grow out, and two years to get secondary, perhaps tertiary branches in place. In 5 years, it's a much better tree.
If he chooses to not air layer, then year one, chop off all of the branches and let the new ones grow wild. Branches are selected and left to grow to the preferred thickness in year 2. In year 2, you can work on the apex by controlling the growth up top while the bottom half of the tree is left to grow. Year three, cut the bottom back, then years 4 and 5 is spent on ramification. Carving out the reverse taper can occur in any of the years. Once again, an excellent tree in 5 years.
