Is there any way I  could easily swap one model's animation to another? For example, swapping Alleria's animations with the Blood Elf model that has way more animations added in BfA, without going through the very, very long process of rigging it in Blender? I know there was an animation-swapping tool in the past, but the links seem to be dead and I'm not even sure it would work with this kind of thing.

If you want alleria to have anims of belf either change armature or pickup animation sequences from belf insert it to alleria and check bones relations
