Trinket Slot And Pink Ward Suggestion

I personally feel like after all 6 normal slots are filled up, players should be given the option to change out their standard trinket for a pink ward on a 3 minute timer like the old green wards.

What would this accomplish?

The player would have to choose to have a sweeper which can clear enemy vision, a blue trinket which can give multiple indefinite vision "wards" until an enemy destroys it, or a pink ward that is capable of being dropped in the middle of a battle to help counter something like vaynes ult, or shaco ( p.s. im a shaco main ), or help combat stealth in general.

The reason for the purchasable THREE MINUTE TIMER pink ward would be so it cant grant infinite duration like current pink wards do, and would be primarily used for a skirmish or centralized battle.

This secondary "pink" on a 3 minute timer would also count as 1 in the "only 1 pink ward per player on the map at a time" thus a player couldnt stand a regular pink and this 3 minute life span pink.

As a stealth player, i feel like this option should be available because it forces players to give up red or blue for something that doesnt last longer than 3 minutes, they should only be able to hold 1, and have to base to refill it making it a very very niche but much needed item in specific situations
