Re: is she ever going to eat solids?
My son had difficulty with solids, and wasn't able to eat them successfully until he was 2 years old. At one point he went to an occupational therapist who said that, when a baby is having difficulty swallowing solids without gagging and choking it is important to allow the baby to experience the food with all of their senses -- in other words, let them play with the food, don't try to feed them. She recommended providing a variety of different types and textures of food on a regular basis, and allowing baby to just experiment with them to find what suits them and to get comfortable with food, since many develop some aversion if they have been encouraged to eat when it doesn't feel alright for them.
We were already doing those things, so she just encouraged us to continue, which we did. We also eventually sought the help of a Chinese Medicine Practitioner, and, as I said, around the time he turned two, something clicked into place and he has not had any trouble with solids since.
I must add, however, that we were already in the midst of many diagnostic procedures for various health issues my son had, and I would certainly recommend that specific physical problems be ruled out in your child's case. The doctor who suggested that you cut back on breastmilk to encourage her to eat solids is not hearing your full concern -- you are, as I understand it, not concerned that she isn't wanting solids due to lack of hunger. I am understanding you to be concerned about the fact that she doesn't enjoy eating solids because she always gags on them. I would be sure to either make that very clear to the doctor, or find another doctor who is able to listen to you.

Those who say it can't be done should not interrupt the person doing it.
