Why hasn't anyone made a game using koikatsu's card tech?

I'm actually very surprised nobody has yet.

I've seem dozens of ren'py VNs using imagery from koikatsu, but never the tech itself to be able to customize the characters, and i'm confused because I'd think that it'd save a ton of time in character modeling and make character model swaps way easier for everyone since there is already hundreds of thousands of KK cards.

Afaik Illusion declared bankrupcy back in like 2023 and even if they rebranded as Illgames, i don't know if legally they'd still be able to press charges for their old company. I have no clue when it comes to patent laws as you can see, hehe

We are also aware of how the rigs of the models work even within the actual game itself, as we've seen with stuff such as kplug, and the engine it runs on is Unity which is greately documented.

So why hasn't anyone tried it? Legal matters? Tons of work? Plain old didn't think about it?

I think you have some errors in your logic, especially with how you think the card system works. The card system stores metadata about character customizations in the image itself; The game then takes that metadata and loads the customization settings along with the IDs of the hair, clothes, etc to construct that character.

If you want to create a Koikatsu game with the ability to allow people to customize characters, you'd have to build your own engine capable of interpreting those values and reconstructing the characters from metadata, AND also have to package all of those same exact mods from Koikatsu so you have the right resources to load up when someone does use those resources to customize their characters. You'd end up with a 200GB game with all the mods from Koikatsu.

Ah, sorry, I worded myself pretty poorly there. I know how cards work and that most are meant to have extra mods that have to be manually inserted into the mods file. i meant just ripping the character creator off the vanilla files itself, so those hundreds of cards and mods for said cards have more purposes than KK and the charastudio, because some characters are so beautifully done that they look like they were straight up pulled from the original source

I mean, heroine rumble and other enlit3D games have a system like that.
as for the part about them straight up using kk's engine/system. it's commercial/legal suicide, plus if the actual studio didn't do it, it means that the engine on which the game is running, is probs not made for it.
