Re-targeting animation - Is the original AnimBP a Parent?

I’m currently working on creating my second NPC character based on the first character’s master class. Because the characters are of a different size, I need to re-target the animations. I’m wondering if when I re-target the animations, will the new Animation Blueprint become a child of the original, or will the two characters completely diverge from that point? I’m trying to save myself work and if they diverge, it means I have to do twice the work in the future when it comes to modifying the Animation Blueprint.
