Nice to see some new textures for these

You can recolor these bottles just like any other CC object, so there shouldn't be a need to overwrite the textures on the original files, or to give them a different GUID. They're quite neat like that. They also work for infants, but that's an avoidable issue ingame.

I had to make the fixed files separate from the original because for whatever reason the textures would show up white for a lot of people (tried to fix it, but didn't figure out how back then - probably would've had better luck with it now, though).

Oh! I didn't know you were the same person, I've seen you around in the forums and never made the connection!
I hope more recolours are made too - this was just a personal project initially until I had some friends encourage me to upload it, and that's why I rewrote the textures. It'd be so lovely to see more recolours of these!
Originally the Simotized ones I had were showing up white, yes! Would it be better for you if I removed the mesh from the download and linked to where I got yours?

I saw your post, and thought I'd go back and have a look at the original, but couldn't figure out the issue. Simotized did upload a fixed version at some point, although I can't remember quite if someone said this also had the texture issue. It's possible whatever was wrong with the original was fixed in that version.

I noticed while poking around in the file that the mesh has some issues with the smoothing/normals, so I was actually working on a fix to the mesh file, possibly a tiny fix to the UVs too (maybe just unwrapping the whole round part of the bottle, so you can use patterns or recolor the sides without any mirroring). Thought that could make the recoloring a bit easier (I'll add an UVmap).

I don't mind if you have the mesh included in the file, but it's nice if you include a link to my site
