Though a nice idea I don't think this can ever be implemented.

The Dorans items are extremely cost efficient. They can be so efficient, because they have no buildpath and have a very low sell value. So basically you either buy something that gives an edge over your opponent but stays in your inventory. Or something that makes sure that you can buy your next item sooner but gives inferior stats.
