Hextech Box Craft Idea

anyone who has bought one of those Hextech Chests have been disappointed by what their loot. getting a skin of a champion you don't even own, or getting only a shard of what you want. So how about this: have types of Chests you can buy. Different Chests in which you choose what kind of loot you want.

Like for example, lets say I want Tahm Kench. Then I would buy either a Support Chest or a Tank Chest, since that's what his roles are. Or a Bilgewater Chest since that where hes from.

now lets say I want a Mecha Sion skin. then I would buy a Skin Chest, or Mecha Chest (which would more expensive than the Skin Chest)

What do you think? this would make Hextech craft a lot more awarding right?
