I have an Ultimate skin idea but...

It's for Udyr so it probably won't be made but I felt like sharing it anyways

ADVENTURER UDYR http://pre02.deviantart.net/0af4/th/pre/i/2013/299/5/9/cronicas_rpg_by_caiomm-d6rvknz.jpg

Each form is a different class and he would use different weapons

Tiger would be Rogue(daggers)

Turtle would be knight/paladin (shield bash)

Bear would be Dwarvan warrior (hammer)

Phoenix would be mage(staff) http://vignette2.wikia.nocookie.net/leagueoflegends/images/b/b4/The_Brutalizer_item.png/revision/latest?cb=20130319091603

Like spirit guard udyr with each point into the ability it began to change it look they essential get better gears as you put level into it

But since we can't have this I would be ok with a 975 skin without the weapons or evolving gear.
