I think if he would use it then it would be easier. I got some disposable, biodegradable litterboxes that you can throw away when you would normally change the litter and then put another one out. You still have to scoop though. I really liked them, but they were too small so I can't use them.
I have seen these liners that are made to make scooping easier. You put a group down in your litterbox and peel off one layer to "scoop" it. It has holes in it so the litter goes through and back into the box on top of the liner below it. There's enough holey ones to "scoop" 3x a day for a week, then there's one without holes to take all the litter out. I don't remember where I saw them.
