I would try to horizontally stretch wet and lay down the reverse curve at the top and dry shrink the rest of the bottom with two people using the Ryk method.
I would also lay the glass on an old tire or something to elevate it and keep it from sliding. A PDR or body shop hood stand would be optimal for 360 access. I keep a few glass installer style suction cups and tie straps for loose glass that comes in to keep em from sliding around. Good Luck, please post your win when you get it!
