You can make attire hacks with activators which focus on other body parts and their colors for VPW2, it works similar in No mercy to.
Player Specific Attires.
Colour Values
I can imagine it being something like.
If P1's Ring Attire Left Trunk Texture is Val Referee (for the skirt poly base)
D10A9F90 (I don't know the value)
And if P1's Ring Attire Trunk Groin Color is Yellow and Purple
D10A9F92 0608
And if P1's Mask texture is AKI Man
D10AA0e0
You'd have to rewrite the code to...
<blockquote class='quote\\_blockquote'><dl><dt>Quote:</dt><dd> </dd></dl><div>
Ring Attire P1
810A9F94 Left Trunks
810A9F98 Stomach
810A9F9C Lower Back
810A9FA0 Chest
etc found at Player Specific Attires link

...instead though even if that is quite time consuming,
And you'd have to make the code P1-P4 converted.
Oh and remember to leave changing the Right Trunks till last though otherwise it won't work.
Edit: If you don't make it character specific then your team or people who downloaded him as a MPK, can move him round him around freely.
