I remember that article, and they said "rework," they didn't specify GU or VGU. However, if you wholeheartedly believe that Morgana just needs a GU, you are sadly mistaken. She looks hideous, and she desperately needs a VGU to her to a modern place. Hell, I didn't even know she had feet or legs under her dress until there was a bug in the game that made them clip her skirt during certain animations, and that's just sad.
As for her kit, Morgana has a bipolar kit, much like Old Galio. The majority of her playstyle is dull and involves fishing with Q to plunk W under people. This directly conflicts with her R, which tells you "HEY GUYS, I NEED TO GO UP AND PUNCH THEM IN THE FACE," which gives her this disjointed kit that doesn't really flow with itself. And Black Shield, while iconic to Morgana, is honestly one of the most OP shields in the game. It's got WAY too much going on to be a basic ability, in my opinion, and I think it could use some trimming, or some being moved to be a part of a new ultimate on her. And other champions do have elements of Black Shield, such as Master Yi (ultimate) and Camille (passive AP shield), but no one has them together, which is think is a bit too powerful.
