Changing that single block to a double may work, but I'd worry a bit about the two different leads (from the current halyard on the mast and from the vang, which would typically run low from the base of the mast.
Depending on the vang, you might get away with simply a deck organizer, and run direct from the vang to that, leading the vang on the inside. Leave the halyard in the standup, lead it through the second sheave on the organizer. If you're going to do that I'd get a triple organizer for the future.
