Using floor leveler for an uneven hallway floor

[TomM in NY]

I need to level out a 1/4" hump in a floor in my hallway. The subfloor is 1/2" plywood then 1/2" partical board on top. I pulled off the the partical board hoping the hump was just in that but the plywood is humped up as well. I was going to add a 1/4" of luan plywood or hardboard and then put floor leveler on the top then put laminate flooring on top of that. Does this sound like a good idea?

If the hump is not that wide or long and it is the only one I would use a belt sander to level it out. Floor leveler is fine but a little hard to work with. If not mixed and applied right you may have to sand it too.
