If your finisher is any good it won't be a problem. Need to be careful on taping and it will take at least and extra pass to fix the gaps. The problem most dry wall finishers have is the  time to dry that gap. they are used to a tight gap,it takes little mud and drys quick. If they do that on yours and don't let dry COMPLETELY betweens coats it will crack. So when they coat it the first time,slow them down a day or two and turn up the heat.  Aside from that it will turn out ok.  Should take three or four passes each time going to a bigger knife. Last on will be a 12 or 18 knife. Make sure they use corner bead where needed. Amazing what a good taper and finisher can do. Brother in law does it for a living and is a stickler for quality.  You need patience and speed at the same time, especially doing ceiling designs. Slow enough to do a good job,while fast enough the mud doesn't dry and flake.

 Shouldn't see any knife marks or dimples from screws when they are done.
