Oh, I've just remembered. I'm going to need you to send me any stat changes or Move changes on Hibiki since her transformation so I can update my list accordingly. I want to try and keep all Genetically altered Pokemon balanced, so we don't have a point where Genetics overshadow Legendarys or Mythicals. An image or appearance would also be a great help to my list.

No stat changes, most likely just gaining some physical Ice moves, like Ice Shard, Icicle Crash, and Icicle Spear, and will change her Ability/Mega Ability to Refrigerate.  As for appearance change, base form stays mostly the same, just the yellow parts are now light blue, and the fluff on the ears is a bit fluffier.  Biggest appearance change comes with Mega Lopunny, where instead of looking like a 1980's areobics instructor, it furthers the model look. with the fluff on her arms growing into a full light blue fur coat that goes down to the ground, with icicle heals forming on her feet, and the ears coming together over her shoulder like long hair.  Something kind of like this

Also, Mega Evolution retains secondary fighting type, so Ice/Fighting, while her base form is pure Ice.
