No one here can 'plan' your chin wing for you and what ever you plan for yourself might not be totally in sync with some of the realities of chin wings. Here are some realities of chin wings:
1: People with very high 'sloped' mandibles and also very narrow mandible bodies, (you have a very high sloped mandible and also a narrow mandibular body) aren't ideal candidates for the chin wing. That's because it's hard for them (CW doctors) to angle up the cut on a high sloped mandible and there can be little space between where the NERVE is and where the cut needs to be. So, FIRST your candidacy for the CW needs to be established by the doctor as to how close the NERVE is to the cutting device to perform the osteotomy of the mandibular border.
2: In candidates where they can and do cut all the way through to the back angle of the jaw, they can move the segment down and also forward. But when they move the segment forward, part of the back angle also comes forward with that. So, you can't expect to have your back jaw angle look exactly like it does now. It can get a little 'blunted' with the forward movement of the mandibular border segment.
3: As to PRYING out laterally the segment as is shown in your link (to someone else's bone structure), how much they can pry outward like that would depend on the thickness of the segment and also the ELASTICITY of it. So, if the segment is just a thin sliver, (for example in a person who has narrow mandibular body and a high sloped mandible), there's only so much they can PRY the segment outward before it SNAPS/breaks.
That said, I'm not trying to dissuade you or scare you about a chin wing. But I do think you should CROSS REFERENCE your expectations with a chin wing doctor as to all these things you want to get out of it.
Have you actually CONSULTED with a chin wing doctor? It doesn't sound like you have. If you haven't, get back to us when you get an assessment of your candidacy for it and also what movements/displacements they said can be done for you.
