How might the reader's impression of Aunt Alexandra be different if Lee had written the story in 3rd person?

n 3rd person omniscient we would have been able to understand Aunt Alexandra better from the beginning. The author could have shifted to her point of view. We would, however, loose the development of Aunt Alexandra through Scout's eyes.Although Aunt Alexandra has her faults there is still much about her that reflects her brother. This isn't fleshed out until much later in the book. This progression is made all the more poignant because it is noticed by Scout.

3rd person omniscient explains the story cause scout's telling the story. But it's also 1st person because Scout says "I" in her sentences so it's shifting from 3rd person omniscient to 1st person. The author also could've shifted her point of view because the development of Aunt Alexandria has her faults there is still much to develop. Ugh! Sorry... I'm muffed.
