Modding Help Custom Child NPC Seasonal Portrait Issues

Hey all, I recently drew up portraits for my kid(s) and Shane and want to stick them in the game. I've had success in planting Shane's in another mod folder, but for the kids, what I did is draw them at 4x(?) and am using a pytk.json that other portrait modders (specifically talkohlooey) use so that it scales into frame, directly replacing the original portrait assets in the mod's folder (NPC Child for SVE)
I'm not sure why, but I wasn't able to get the outfits to load separately onto the bases and used the applied outfit as the base instead. I now notice the issue in my SMAPI log reading:

[Content Patcher] unhandled exception applying patch: seasonal kid take after spouse NPC sprites and portraites > Child 1 boy clothes Portraits weather.
System.InvalidCastException: Can't replace loaded asset of type PyTK.Types.ScaledTexture2D with value of type PyTK.Types.MappedTexture2D. The new type must be compatible to prevent game errors.

I can assume this is in regards to the scale ptyk.json, naturally, but I don't exactly understand what the types mean. The file only contains

{
"Scale": 4,
}

I don't really understand why it's giving an error, what can I do to make it work without error?
Would like to bundle together these portraits and share them, but clearly I have no idea how to do this lol... ^^;
