I'd like to answer my own question in case someone comes across this thread. Apparently with a good frame and overlay you can easily "mask" 3D portrait to appear as circular or hexagonal. I used the unit frame textures from Azerite UI and it looks great. So all you need are a thick unit frame texture and a circular fade texture. Combining these will have a very natural appearance.
But if you want a very thin portrait frame, you are out of luck. It doesn't seem possible, I've kept searching for weeks.
