If you mean, can you cancel your listing, wait a day, and then relist as a D1, yes I suppose you could. But, that would have to be at least 48 hours prior to departure before anyone could even check-in; so, you wouldn't have a clue as to where you would stand on the list anyway? What would be the point?
When you go to the Non-Rev travel planner, it will show you the real-time revenue load by cabin--for instance, F/C 7/16 means 7 revenue for 16 seats. F/C 7/16(4) means 16 seats in F/C with 7 Revenue and 4 non-revs. And, if you click on the "I" (for information) button, it will tell you how many of those 4 are D1, D2,, or D3. But, that is just a listing (think reservation). If all 4 are D2 and you are in a "must travel" situation, you would probably want to use one of your 4 D1s. If you have already used all of your D1s for the year, then it would be a good idea to be at your computer 24 hours in advance ready to check in at the first magic moment. At 24 hours prior to departure, you would still have the opportunity to be #1 on the non-rev portion of the Standby list if you are at your computer checking in at the right time.
Also, remember that no seat is taken out of inventory until you actually board the flight. If you are not at the gate when your name is called, the next person on the list gets the seat, and an NR (no response) goes next to your listing. But, if the load is not full, you have already had a seat assigned to you by the computer. It showed you that when you checked in. If you don't show up, the agents have to confirm that you are not on board then they can re-assign the seat to another non-rev. Don't be a no-show if you can possibly avoid it. Agents don't really like extra work.
