Might do that when I get around to reading the documentation for making script mods.

Make her a adventurer/npc

You can already apply this PCC to any NPC in your faction at the resident board.

As for NPCs outside of your faction (Mothers I assume), due to the non PCC sprites having a higher pixel density, applying the forward facing sprite from this mod to them creates comically small Mothers.
If you are fine with this, I've updated the resources folder to contain an image objC_1811.png. Move that from the Resources folder into the Texture Replace folder and it should just work.

As for forcing the full PCC onto all Mothers, I have no idea how to do that and any help pointing me to a relevant resource would be great.

cool but can u add as a npc?

yes
