No. Both flashback and the zero cost of As Foretold are alternative costs, of which you can only apply one to any given spell. Since in order to cast the spell at all you have to use flashack, you cannot apply As Foretold anymore. And since the flashback cost is nonexistent, because the mana cost is nonexistent, you cannot cast Ancestral Vision from the graveyard with these cards.
