Hey, if you're still interested in that Ultra/Luxury ball Hippo in gen 6, I can do it for you BUT:
1) It would be from an emulator file of BW/BW2
2) It would be an injected dream world pokemon
So it would be legal, not legitimate (not genned or hacked though). I can RNG its IVs and nature and show you screenshots. It just depends if you're okay with the above. If not, I understand, just thought I'd offer to help.
