Make the trinket slot double as a place for other items. (control wards, potions)

What if the trinket slot could be used for more then just trinkets?

Allow for the switching out of the trinket with other consumable items in the trinket slot, such as control wards or even potions if people want that. That way people will be able to carry such things even if they are full build or close to it.

I don't know how useful this really is, but it would allow for the taking of control wards in the late game without having to expand the UI by adding extra slots. I doubt I would ever use it given the penalty for selling a trinket (120 second cooldown on trinket use when sold), but some people seem to want to be able to carry extra stuff even when they have full build.

So how about it folk? Would you give up the use of your trinket for a place to store control wards? (Or other consumables?)
