Can I Double-up on Drywall Layers?

Hello, I just took down a wall between the kitchen and dining room. See photos.
1) First photo below: On the photo showing the wall section adjacent to pantry shelves...I need to extend the wall by another half inch to match cabinets to be installed. You can see in the photo that there is drywall attached. To extend this wall section out another 1/2 inch, can I just tack on a second layer of drywall or should I take off the drywall currently there and put up a slim wood board and then attach the drywall piece? This is a question of whether I can double-up the drywall boards when needed or if I need the support of a wood board.
2) Second photo showing the ceiling with crown molding...same question. There is drywall attached but there is a large gap between the drywall to the crown molding. Can I just tack on another layer of drywall to fill the gap before mudding?
Thanks to all.

Yes you can add more drywall on top. You just need longer drywall screws. But if 1/2" drywall is too thick you might be better off removing and shimming the framing instead. Whatever you do you want it to be as close to flush with the existing as you can possibly get it.

And adding another layer of drywall will present a problem on your corner bead installation unless you plan to use the kind that is glued on, or the kind of bead with paper tape.
