Cowboy Bebop Playermodels (PS2)

It has recently come to my attention that there was a Japan exclusive PS2 Cowboy Bebop game. To be quite frank, Cowboy Bebop is awesome, and the models in this game are actually pretty high quality for the time the game was released. Just take a look at these models.

Now, I don’t have any experience making models from existing models, or making models for gmod in general. However, I know it’s possible with a little hard work.
I can’t tell you exactly where to get the game, but I bet you could figure out a way by searching “Cowboy Bebop: Tsuioku no Serenade” or “Cowboy Bebop: Serenade of Reminiscence” on google.

I was hoping for the 4 main characters as player models, as well as ragdolls. Also, I’d also like Ein the dog as a ragdoll.
So that’s Spike, Jet, Faye, and Ed as playermodels AND ragdolls. As well as Ein as a ragdoll.
If anyone needs references for what each character looks like or any leads on actually extracting the models, then I can help with that.
