They've done that before, but only for a few, non-set cards.

From their perspective, it doesn't really make sense. Half of their business model is enforcing a sense of scarcity and urgency--basically, if I don't complete this set, now, during this event, then I'll never be able to complete it, so I better spend whatever I have to in order to win.

On the other side of it, an event centered around filling in missing cards would be awesome for the players who participated in previous events but didn't get everything, but it would be hard to structure it in a way that doesn't put off players at the low end and very high end. Players who completed their sets wouldn't get anything special out of the event: They'd get more copies for Exciting, but they can do that in any event. On the other side, new players wouldn't get much out of an event if the prizes were a mix of week 3 cards from a few different past events. If anything, they get a chance to win the frustration of earning their own incomplete sets.
