Oil Spill Nami Skin Idea

This is a concept I thought would be cool for Nami fans.

Her skin could change, maybe she could wear a bucket over her head? (I think trundle use to have a skin similar to this) and have some blacks and purples on her body?

Q- Throws black bubbles and when it splashes it would be brownish, maybe some blues, purples?

W- Heals target with dark water

E- 3 oily orbs

R- Launches a huge wave of dirty water with garbage, dead fishes. Etc

What do you guys think? (In tribute to the old trundle)
