Yeah I definitely am close to scheduling it. If he recommended it, then it's probably a good idea right? You ever of this being done?
Taban's results are pretty good. He, like other oculoplastics, has a very low risk threshold. IMO, much lower than most maxillofacial surgeons. Most of his work is quite the opposite - making eyes less prominent. Even so, I think it still gives him a lot more experience than everybody else on how the eyes look when the orbital volume changes.
How close set the eyes are is a function of eye width. If less than an eye width fits between your eyes, they are close set. If more - wide set. I don't think this surgery has any impact on eye width, and definitely has no effect on the distance between your eyes.
I would ask him if the surgery is reversible and if he would reverse it for free given, how on the fence he's about the whole thing. I'm kind of thinking he wants you as an experiment. So if your case works out, he'll start offering it more. Hell, I'd ask him to do the surgery (and any revision) for free or for a much reduced price.
If it does work out, it could be a game changer for your looks. The eyes are the windows to the soul. Chins, "gonial angles" are small details in comparison.
