New Hybrid Item Idea

What if there was an item in league which when you cast it swaps your attack damage and ability power at a lower ratio for a set amount of time.

For example, lets say a champion, any champion has 260 ad and 0 ap.

He uses the item and now his ad is converted at a 1:1 rate because ad is naturally harder to get, but if he had 500 ap for example it would be converted at a lower rate, something like .5 and get 250 ad from the 500 ap, a ratio to the point where this item isn't gamebreaking but adds a fun new mechanic to the game.

This item would probably be a mid game item, giving similar stats to the old trinity force when it gave ap.

People who could use this would be people with ad and ap scalings, and playstyles that would work well together, Examples are;

Ezreal could build ad, use the item, cast his ult and w, and become ad again making his teamfights stronger although that would require good timing with the item.

Evenlynn could ult and use her q a couple times and then cast it so her e and autos would deal more damage on to one target, letting her burst more effectively but less damage overall

Kogmaw could start off ad, deal a lot of damage, use the item and then his ult does a lot of damage in teamfights. He'd be kind of like jhin.

is also a good example, he's similar to kog'maw.

Overall this is just a cool idea for a new item, I don't know if it was previously thought of but I think it's a really cool idea. It would offer a new playstyle to the game and make it genuinely more interesting.

p.s if you don't agree with what I think about the champions playstyles pls no hate these are just examples and I'm by no means an expert or a pro player.
