I'd respect it. If well-made on the storytelling and dramatic levels, I'd be intellectually dishonest not to.
But I don't think I'd like it, not nearly as much as Starco. One reason is that it would be like, oh, taking a big gulp of hot chocolate and getting coffee - not bad itself, except not the taste I was expecting.
Another is that a not-insignificant factor in the show's appeal to me is that it looks like it could be, in part, a sort of love letter from Daron to her husband, which would make it super-cute. I mean, Gravity Falls only really caught my interest when I found out that Alex Hirsch had a twin sister, and suddenly there was a new dimension of sweetness to what I was peripherally aware of before. (Let's set aside how that one turned out.) If that ISN'T where Star Vs. is going; if there isn't supposed to be any inspired-by-a-true-story sweetness inside, that's totally legitimate, but I'd be a bit disappointed.
