Map Skins

So this idea has most likely gone on for a while but I feel that there should be different skins for Summoners Rift Like one could be Lava and the river would be lava and Baron would spit fire at you (just an example) but I feel like there could be some cool stuff with skins. Another one i thought of is Stone where Baron and Dragon would be Giant Golems or something but please please please can we have skins for the maps.
