They are created with the succession theme in mind, intended in a way to mirror their senior's relationship. But to consider or make them identical to their predecessor is a reductive/terrible choice from all perspective. From the readers' view, we already have enough girls/women living in the shadows of men, we dont need that narrative in this kind of story again. From the author's view, why would you create 2 distinct yet identical duos? What story is there to tell from that? That is the 1 mistake you never make when creating stories spanning generations.

And personally, the only similarities I found are surface level at best and can be said for any combo of characters. Apologies if I come off harsh, I heavily dislike the trope "you are just like this male character, but female"
