Pocahontas doesn't suck, and the peak of the Disney Renaissance continues?
Problem is, there's nothing you can do to the original premise to tweak it to make it any better.
If you introduce Pocahantas' actual groom John Rolfe, you make the narrative too clunky by violating the Principle of Minimalism. If you age her down to her actual contact age of twelve, "Colors of the Wind" would turn her into an underage yandere and Captain or Liutenant John into a pedophile. And adding the John Candy talking turkey character that was written out of the final draft of the script woyld be like adding Br'er Rabbit to a Disney Animated Musical of
Uncle Tom's Cabin.
If you make it into the Tragedy the real life version actually is, it would win the Palm D'Or at Cannes, and the Blue Ribbon at Sundance, and maybe even the Best Picture Oscar that was denied to
Beauty and the Beast, and then flop hard with American audiences for the same reason
Grave of the Fireflies and
Here and Now and Then and There did when released on video.*
Walt Disney Studios' animation division is simply too big to make true cult classics that don't rely on camp. Their economic model simply won't support it.
So, instead, how about... well, no, an animated
Three Musketters would have been perfect (and I could have sworn that Disney actually did one in the Sixties, but that turned out to have been Freling-DePattie) except that it would have suffered from comparisons to the Live Action movie version the way the Disney version of the Twelve Labors did to
Hercules: The Legendary Journies.
So, which animated film does Disney do instead?
*That said, I would have loved for such a film to have been made, with the closing credits done to Niel Young's "Marlon Brando, Pocohantas, and Me."
