No, the new cards can't help you hit the threshold of Transformative Sacrifice, since the threshold only does something when Removing Presence, which happens before any of the cards are played.
They also can't help with thresholds on Powers that were already used, since Transformative sacrifice doesn't let you time travel back to when you used the Power in order to give you Elements at that point. Transformative Sacrifice should almost always be the first Power you use in a turn.
