I don't know if it will make your final breast size greater - I think we get what we get, personally, just like cis girls - but it should give you a head start on growth.
I was similar, and I had breast buds and visible growth within the first week, and was fitting into a 42D bra by the end of a year. I seem to recall hearing that cis girls in puberty generally spend a year or two with breast tissue ramping up to be ready to grow, and then it really takes off; the impression I get is that those of us with gynecomastia may have already accomplished that "prep phase."
If nothing else, it does suggest you're very sensitive to E, which is also a good thing!
