New champion/s Animation idea

Well I was up watching, an epsiode of super-natural, and thinking about my new champion's I'd recently bought when this idea came into my mind. First let me say sorry if this is posted in the wrong place.

Basically here's my idea, Kill trophies placed on the map. They would offer no stat wise advantage but When you kill someone with your ult(or in ult form in some champs cases) A Champion Tombstone would be placed.

Tombstones would vary from champion to champion. For example Elise when killing someone in spider form would leave a Cacoon behind where they died. Cass would leave a stone statue of an the enemy champion only grey. Garen could leave a sword stabbed into the ground ect....

Let me say once again these tombstones would be icons only meaning none selectable no stat game ect... Roit I know there maybe a consern to a clustered field ect.. That being said You could make them last like vision wards in the respect they disappear after 3 mins. Not that they would give sight of course.

The only effect on the game I can possible for see would be teams would have a marker where they were prieviously ganked lol. It might acutally tell some feeders not to go there anymore.

While I know nothing like this would happen right away, or might not ever I do however believe it would add a fun element to the game.
