Not that I know of...no way I can think of since WAFL isn't like a local file system with utilties can undelete... There is one possible exception... if you run "snap list -A" are there any recent aggregate snapshots? If there are, you could restore the aggregate or aggr copy the aggregate from that snapshot and see if the file is in the volume from the aggregate snapshot...that does require a full restore or full copy out of the containing aggregate though.
