Some things about the Son of He-Man pitch seem undercooked to me.

Dare is at least 12 years old and someone stole him from his parents 10 years ago, the same time Adam got married. King Adam and his queen have to be childless until they adopt Dare (presumably Scheimer didn't want to clutter the narrative with siblings for the hero). So is Adam infertile? I guess that would work in a kids' cartoon, since it's a recurring plot point in fairy tales.
A bigger problem is that the answer to the "Who are my parents?" mystery box was going to be Adora and Sea Hawk, "an unsolved mystery until the very last episode."
So Adam had lost contact with his only sibling, the heroine of Etheria, for at least 10 years plus the run of this show? The retired Randor and Marlena lost her AGAIN? And what happened to the Horde?

The pitch treats Orko as a main character who still has "a girlfriend, Dree Elle, back on Trolla". Geez Lou, it's been at least 12 years since the last She-Ra episode, let these two get married and reproduce.

Kayla is just a xerox of Teela, fair-haired warrior woman related to Man-At-Arms. You easily could and should make the main good girl something different.
