Ich schmeis mal random was rein.
Here's my fan theory of why Lyra Heartstrings did not appear in the movie as a human:Leider sehr unwahrscheinlich, trotzdem interessant :)
Every human is Equestria Girls is a counterpart of a Pony in Equestria. Except for the ones that are Ponies transformed into humans, like Twilight and Sunset Shimmer.
The reason Lyra Heartstrings is not in Equestria Girls as a Human is because... Lyra Heartstrings IS a Human in Pony form living in Equestria!
If we look closely, we can see that there are two Lyras in Equestria, and both act completely different from each other. One, let's call her Lyra A, is the one we see in Canterlot, she lives there, goes to the school of gifted unicorns, participated in the play for Hearts Warming Eve, and was a bridesmaid for Princess Cadance, and we never see Bon Bon close to that one.
Then there's Lyra B, this one lives in Ponyville, we see her always with Bon Bon, participates in different events, got her pie eaten by a Parasprite and sits down on a bench like a human would.
Lyra A is the original pony Lyra, born in Equestria as a unicorn, raised in Canterlot. She never heard about human, she does not care about humans.
Lyra B is Human Lyra, that got tossed into the portal by accident when she was a baby and so only remembers Humans in vague memories and actions, like sitting on a bench, she transformed into a unicorn when she fell in the portal, and was adopted by a family in Ponyville where she now lives after having growing up.
