Mini Wings recolours, yes. I'd personally be fine with any colour that's reasonably easy to match. Hell, make ALL the colours, I'd buy them all.
Though personally, I'd like more DJ recolours. Because I'd like DJs for every occasion.
Also, inverted AFKs, OMGs, BTKs, and OMFGs would probably make my life.
EDIT: I'd cry tears of blood as payment for more Hatter recolours. Though that's probably wishful thinking on my part.
