Surprise; I actually made a model... sort of, since it's really more of an edit of the Alex skin that I added onto. I've probably spent way too long on (3 to 4 hours or so) trying to make a model of one of my Bedrock characters that looks like it'd fit within the base game, but in
the end, I'd say I'm decently proud of it and I think it was worth the time.
Included is a time-lapse of my process on modeling and texturing her, starting with a basic skin, adding details when necessary to make her more of my own character rather than some assets thrown together.
Here's some raw images of her as well, including a turnaround:

This is Kit, and I'd say that she's probably a bit of a Minecraft-sona or so... granted, there's no way that you're going to be able to see all of this
in vanilla Java, and the basic idea for her was mostly that I bought some accessories on the Minecraft marketplace for Bedrock and made a character I really liked, so I decided to try my hand at modeling and texturing them using a combination of Blockbench and Aseprite, making some modifications to her design as well. As far as I know, there's no easy way to view character skins "freely" in Bedrock and the files themselves can't be viewed in external programs since they're encrypted or something, so I simply just ended up taking some screenshots of my character and used them as reference material for Kit here, although either way I suppose it was probably a blessing in disguise so I wouldn't feel like I'm directly using the in-game textures and the like.I've mostly just settled on her appearance for now and haven't really decided much about her character, if anything, but that might change later on.

If anyone's interested, here's what she looks like in Bedrock with in-game assets for my original inspiration and comparison:
