Is it possible?

So I have this bougie I'm not satidfied with

​

I find ugly the spot where the two branches join. Some months ago I (as a bad beginner) removed a third branch there :

I should have chopped the left one.
I have thought to chop the left branch like this:

​

But I think it could be worse than before....
What I really want is to change that spot to become something like this:

​

Is it possible to thick those spots through some kind of work? Can you see any other solution to improve that spot or the tree?​

How about.. tilt 15 degrees to the right, and lop the right hand off, build a new tree with what is not the low left branch?

Even though I don't completly understand your proposal, changing the angle can be key to improve the tree...

What I had in mind ( a nonsense likely) about thickening the ugly spot was to create some scars in some spots, so the healing would produce some kind of growth.....

Ok, now I see what you say. It could be a good solution, but I would fear to create an ugly elbow (I'm unexperienced)

Also, could I create a little shari in that spot, carving to create an armonius flow to the branches? If I fail I can try your solution

It is possible to cause local thickening on trunks of many species.
Small wound cause callus which grows at greater rate than the rest of the trunk to give localized thickening.
The first time I heard of this was to gently hammer the trunk where thickening was required. The damage causes callus under the bark.
Next, and one I have used, is to make cuts through the bark to cause callus and healing. I've used a series of cuts running parallel with the growth ie up and down the trunk where you want it to thicken. Each year new cuts are made until required extra thickness is achieved.

Not sure if that's what you want or whether that would be good in this case. Thickening the trunk around that fork will still leave the lower trunk thin so you will still have reverse taper but even worse. Treating the trunk below the fork might be a better proposition.
Note that it is too cold here for bougies so I have never tried this technique with that species.

The biggest problem I see with the tree is straight sections of trunk with a small dogleg bend and little taper. I cannot see any short term solution from the photos as shown. @leatherback proposal is a good plan - solves both straight trunk and taper - but will take quite a long time to achieve. The top section may be better starting material so layer or strike it as a cutting when making the chop could be another option.

Not sure that carving will be good on a bougie. I think the wood is soft and rots quick so a shari will soon turn to a hollow.

You don't need trunk thickening, you need to cut the left hand branch off, then re-do the trunk chop at a steeper angle. Damaging the trunk to thicken it is a very ineffective way of doing things. Mostly it just doesn't work all that well. Simply rechopping the trunk at a steeper angle --with the leader on the high side of the chop, will force more taper into the trunk, as well as solve that ugly bulge problem.
