Can't see how a hand control will help you as I need both hands quilting. Not knowing your exact set up and not having a picture to look at , I have two ideas. The first is, build a box that won't slide on the floor, and put your foot control on top of that on one of those grippy anchors that will hold the control is place. You can build it as high as needed so you can reach the peddle to push it. The second one is (and this will sound funny)....but how about if you put your foot control under the right side of your upper thigh when sitting on your chair, so all you have to do is lean a bit to the right (or left) and it pushes the control down so you can sew with both hands? You'd have to be sitting in a slightly larger seat that's pretty flat, but try it, it may work. Hope one of the ideas works for you...
