We missed our door of opportunity

At first blush, this one sounds right, but on further inspection, the speaker has apparently blended “window of opportunity” with “when one door closes, another door opens” (or maybe “open door policy”?).  The resulting malaphor certainly makes sense as a window and a door are both openings and both idioms convey similar meanings.    Less verbiage is always a good thing (you can quote me on that).
