Fixing Creatura - The Harpy to work on G3/G8 - What Do?

Panzer Emerald

So, since there's a sore lack of legit bird feet for G3/G8, I figured I'd try to use Creatura - The Harpy (https://www.daz3d.com/creatura-the-harpy-for-victoria-4) on G3/G8 (I'm using G3F here, since I don't have the V4/M4 Clones at this time). In a previous thread, it was said that to fix this, you'd need to adjust the Weight Maps in DS, so the talons don't overlap and then auto-fit doesn't overcompensate for any missing bones or w/e is lost in translation.

Well, here's my question: How in the fresh heck do you do that? 

To be blunt, documentation for how to use Weight Maps is terrible. I've found Blender tutorials to be less obtuse than DS' documentation. I suppose if I was that desperate, I could attempt to MacGuyver and do a re-geografting to G3/G8 in Blender, but that's too much work to do and frankly, I'm lazy, lmao. If someone can help me (and anyone else who's Weight Map Tool Challenged) figure this out in as simplest of terms as humanly possible, please, I would greatly appreciate it. Thank you!!
