My family have a rule that you can pick up the discard pile with a wild and a face card provided that you have already gone down. I feel that should be an option as 'Provided the card can be immediately played.'
We also play that you pick up the value of the face card, so if the top of the discard is a 4 you get 4 cards, 5 (5) 6 (6), Jack (10), Queen (10), King (10), A (11) etc.
