Adding User (Writer) Avatar

What's the chance of adding the user avatar as an option in the "Recent Custom Posts Type Widget". I've hacked it in myself but don't really want it to be overwritten on an update. I'm using it as a sidebar widget for columnists on our news site. It's perfect for my needs with the exception of that one issue.

BTW - I love WPMUDEV and have successfully convinced my past 2 employers on the value of a subscription.
