You might be able to make a code to make yourself look like wario/luigi. Here's a demonstration on how you might be able to create a code for wario:
1) First use a size mod code like:
221b6acd 00000019
221b6ad1 00000022
221b6ad5 00000021
2) And then make a color code to make mario's hat, overalls, and shoes yellow.
3) Add the "heavy mario" code.
