How about a wasp/hornet Kha'Zix theme? maybe to go along with a garden themed 750 release?

Yellow black color scheme with brown/sandy wings, ult version could turn his colors tarantula hawk esque, A dark, royal blue color with burnt orange wings. (Tarantula hawk color scheme for reference http://puu.sh/kDsxv/9b17ece907.png ) Sick wasplike head with compound eyes, and vertical mouth. his spike racks could be large, needle like black stingers, His wings could make a buzzing sound effect when he uses evolved leap, and maybe his walk cycle with evolved leap where he does the small, floaty hops could have a more subdued version of that sound effect added. Neon yellow and black particles with a lot of emphasis on honeycombs, with aggressive buzzing (like the kind you hear near an agitated hive) when he slashes with Q to distinguish from GOTS. (another yellowish skin) passive would be bright yellow, as well, with a faint honeycomb motif on his isolation indicator. and whenever he procs his passive the circle particles on his base skin would turn to honeycombs as well,

Other skins related to the theme for 750 could be for champs like Elise, Zyra, Anivia, etc. champs that can fit into a garden theme really well. maybe could also re-release Caterpillar Kog'Maw with it as well?
