The 3 items, Doran's Shield, Ring, and Blade, should make a mid-tier item similiar to trinity force but only with the aspects of those 3 items. Should be a early / very early mid game item.

No. Doran's items are the most significant things you can start the game with if you choose to get them. The point is that they are placeholder items for something else. You eat about 217 gold (because you should be selling it back to the vendors if you're ever short at all for what you were planning on getting) is all.
