Question Regarding Pokemon Trainer textures and Final Smashes

[Choppasmith]

So I'm really going through my textures for the first time in a couple years, finally adding portraits for the CSS and things have been going good so far until I came to Pokemon Trainer. There's a huge variety of trainer textures now and I love it. My only problem is Final Smash textures. Last I heard, you had to have a special texture called fitpoketrainerfinalXX.pac otherwise the trainer and the pokemon for that slot would revert to their default looks when performing Triple Finish.

Looking through the vault, it seems like while there's a ton of variety now, there seems to be no regard for making Final Smash textures to go with it. Is it just something people don't care about anymore? Was there a change to the FPC? Is there some easy way to make your own in Brawlbox now? Just wondering.
