I've got a line flare press, they're not expensive or hard to use. It wouldn't surprise me if O'Reilly's has one for rent.
Tough situation MO, about the only way I've gotten out of it is to either soak the fitting with some good penetrating oil then work it back and forth with a wrench while continuing to hose it down with the penetrating oil, or like you mentioned cut it out and splice around it.
