Looking for parts for a custom design console?

[u/dappled_sunlight_47]

I have a DSI XL/"LL" (Japanese model), that I want to fully redesign into a special edition Shaymin one. What that would need in my eyes: custom pink buttons, top bezel/bottom bezel in pink, the lime green shell like the one for the smaller DSI. But the thing is I can't find any cases like that out there, there's a good chance they aren't made anywhere but maybe and so I ask on here.
