You have quite a few interesting ideas here, in particular Ring of Oblivion's active, but as the other users here said, they'd work better on proper items than follow-ups to the Doran's item line. The point of Doran's items is to provide massive instant bonuses at the cost of later efficiency, and the upgrades you're proposing are not only great for the mid-game in terms of stats but also have extremely powerful actives. Having these kinds of upgrades would make Doran's purchases so good that they'd be practically mandatory.
