Multiple skins for one champ

Well i guess that people who have been playing for a medium time ( or even less) migh have already more than one skin for a champ, some older or rarer and or a new sick ultimate one, or even own a nice one but they release some other awesome for him. then come the strugle, should i spend on something i already have and even if u do, sometimes u like a skin but the other is ur favorite and u end up never using them,

So, what if they implement the codding they did with new mf skin, where u can swap models and skin when in the respawn plataform, so that people could let those dusty skins out of the closet and give them some air in case they wanted to. i believe that erlyer this could be an issue but with nem mf ultimate skin i belive that if we dont yet, we are very close of the coding tech necessairy for such.
