I don't see the reason why we need 4 options. 2 starters should be enough if offensive stat is made adaptive instead of ad/ap.
Then you could add variation to the items so you can choose the upgrade from different options. The upgrade could be made similiar to Gankplank's silver serpent shop upgrades to his ult. Requiring the champion to actually back before getting wards or other things from the item.
Would be neat to see that you have different variations on the items between games and champions.
