Yes, try using a dremel or cutoff tool across the flats of the nuts. Try to cut it into two semi-circular pieces and pry them apart with a screwdriver in the cuts.

I have hacksawed several of these and haven't ruined any yet. You can cut into the male thread of the cooler a bit without ruining it, but dont go too far or you will cut into the beveled flange that seals with the oil coller hose end.
