Hardly incarnation. Aslan is 100% fictional. A representation, yes. But not an incarnation. Furthermore, God only really has a "gender" because we cannot comprehend Him being without gender, even though God is. "He" serves as a means for us to relate to Him, and to emphasize the spirtual authority structure He set up.

May I remind you, God/Jesus only has a "gender" because we cannot comprehend a genderless being. And Him calling any of the Trinity "He" only serves emphasize the spiritual leadership He set up.

God isn’t even referred to with any "gender" until Gen. 1:27. (v 26 uses us/our which have no gender-- in the way we understand it, or grammatically.) Any gender assignment to the original words [like Elohiem, aka God, in v1] don't actually correspond to sex. As "noun masculine" (et al) is a misunderstanding of the use of "gender."

You do realize that the only reason that God has "gender" is because we humans (then and now) can't comprehend a genderless being, right? Well, that, and the reason for God being "Him" and Jesus being "Son" was to further/emphasize the spiritual leadership structure He set up.

Don't misunderstand though, I'm not necessarily advocating for a female Aslan. It is, however, still entirely fictional.
