Here is something I thought of

So here is something I thought of. As Littlefoot is the one of the five main dinosaurs that keeps on changing voice actors mainly since all of his voice actors are boy kids and many of them hitted puberty which is why Littlefoot's voice actor keeps changing. But what if Littlefoot was voiced by a grown up girl? If he was, what grown up girl would have voiced Littlefoot instead of being voiced by a young boy kid?
