Everything's just a palette swap in this game of the main 1P outfits and the customizations aren't character-specific.
Phoned-in like hell on that front, I'm telling you...
Wait, but I've seen Jin wear his Emperor/Tekken Force T6 custom items...?
I just hope the game comes fully packed for the console port. To start with, they can practically recycle everything T6 had to offer.
And seriously, having a P2 outfit wouldn't hurt them. It could be like the original Tag: 2 color swaps per outfit. Seeing the new customization mode saves in a single palette, that means I could keep 2 customs and the 2 original ones.
