It's a fun rebus-y mechanism. I think Kosman and Picciotto of Out of Left Field did the first version of a clue like that that I saw. If you like new, fun wordplay, they're worth a subscription.
Favorites: 1D, 2D, 4A, 6A and especially 5A. The title clue really got things started. That leaves 3D — I am conflicted. Never would I have solved this without spotting the definition and having the crosses. But I love the willingness to look for new methods of writing a clue. Overall, a very enjoyable solve.
