I would think that a whole range of plug sizes would work. It just needs to get a heating element in the chamber that seals and doesn't have an interference fit with the piston. So what if the heating element isn't the optimal size or have optimal depth placement -any heated point in the combustion chamber is going to help initiate ignition versus a non functional plug.
I purchased a 2 cylinder tractor one time which started/worked just fine -when I replaced the glow plugs as routine maintenance later on I was surprised to find 2 different plug sizes.
If it was my tractor I'd happily gamble eight or ten bucks on the closest NGK part number betting on better starting
