M&L:SSS Boo luigi

[Vipershark]

I think the main question that needs to be asked is

Does Boo Luigi actually exist in an official game? I know Boo Mario does, but if Boo Luigi does I see no reason why it technically /shouldn't/ be accepted, especially considering that luigi himself is basically just a mario recolor.
Is there an M&L Boo Mario on the site already?

Then again, I'm not in charge of submissions so I don't really have any kind of final say there.
Just my two cents.
