No, definitely not as a metadata download plugin.
For the reasons why, see
this thread.
It "could" be done as a standalone UI plugin, but it means repeating a lot of Calibre infrastructure code and maintaining yet another plugin, which I personally am not interested in doing.
If the above state of play concerning custom column support for metadata plugin changes, then I can look to potentially add support for awards downloading to the Goodreads and Fantastic Fiction plugins. However as it isn't a priority for any of the calibre developers AFAIK I wouldn't hold your breath on that.
