They modeled Cortana after her brain, Cortana got to choose her own appearance. She did look at an old picture of Dr. Halsley and choose that. So yes, Cortana looks like a young version of the doctor. However, one thing you failed to consider when making that model is the fact that the doctor is in her 60s to 70s in age. That lady only looks 40. It was mentioned earlier, can't remember where, but by Halo 2's time...Master Chief is 41. Something to keep in mind.
