Without looking, I would say quite likely, you would have to buy another OEM stack valve of that hoe series, and determine which one you want. Whether your existing cover will allow it is something to look at. If there was lots of room, you may even get enough to shove an extra valve in the center and move the joysticks 1/2 inch out each way, and open the center stabilizer slots to one big one to allow three levers. You'll have to do some precise measuring before contemplating.
