I do think my personal enjoyment of the ride would jump up quite a bit if the projected faces were replaced with regular animatronics.
I know they want to push the envelope wherever they can, but to me, an animatronic needs to look convincing (Monsters), charming (Nintendo), or both (Toothless). The projected faces don’t achieve either goal, and I find them to be detrimental to the ride’s storytelling as a result.
