Fetchlands are deck thinners and you can work easily with little mana, specially with Vials around. Remember that Paul Rietzl and Kai Budde managed to top 8 and win GP Amsterdam at a time in which Extended resembled the Modern format a lot. So yeah, White Weenie should be a possible tier 1 deck.
Should AEther Vial get banned or you not have the cash to fork over for it, here's what I'd suggest you:
True, I'm not packing Path to Exile maindeck on either deck. But neither did Rietzl or Budde and they still managed to top 8. Honor of the Pure and Spectral Procession gives you a White Lightning-esque combo. I'm considering testing Proclamation of Rebirth in the Ranger of Eos place. It doesn't tutor for 1cc creatures, but acts as a pseudo Spectral Procession.
