A couple more findings...
Take a close look at the roaring lioness in the foreground
here and
here. It's hard to see, but she looks almost exactly like Zira -- same chin shape, even the same fur strips in the ears. There's also a line across the bridge of her nose, and I've seen that feature appear on characters that have lighter/darker gradients on their noses where there's an animation mistake. I'm attaching lightened versions of the lioness in case the screenshots are too dark to make out:
In the left group of lionesses in this shot, look at the one at the top part of the arc, then look at the lioness to the left of her (the one with the raised paw). That lioness has bangs like Vitani! However, look at the lioness to the left of
her --
that lioness has bright colors. In fact, she's the
only lioness on the Outsider side with bright colors. This all makes me think that the artists accidentally swapped the colors of Vitani and a random Outsider, so no unique Outsiders to be found here. : (
Is Kovu supposed to be nuzzling Nala? It looks more like he's just nuzzling air. He also seems to be getting a lot of attention from those two Outsider lionesses... : /
