Dude, you're overanalyzing a set that literally consists of a mustache and a coat to unimaginable levels.

What

I see where you were going with this item set, and while I do think it looks nice and could be good for animations, it does not fit spy as a character and should not be included in the game.

Spy isn't the type of character to solve mysteries, nor is he the type to look the part, as he is the one creating the mysteries, he's the one murdering people and giving the authorities the headache of a lifetime. Dressing him up like a detective just doesn't suit him in my opinion.
