That won't work with an FT boot, unfortunately. As Ankhou said, they do not have tech fittings so you would be looking at new boots and bindings, which is a steep price for occasional touring. I would recommend looking at non tech AT binders first, like the Fritschi Freeride Pro, Marker Tour F10/F12, Baron, or the Guartian 13 being released for next year. At 135 pounds you likely don't need a 16 DIN like the Duke or current Guardian/Tracker/Adrenalin.
Having said that, I had MFD/FKS for 1 year and put 25 backcountry days on them. I thought they worked great right up until the first day I used my Dynafit setup. Once you go Dynafit, you'll never go back. So if you want to spend the money and dedicate a setup pretty much completely to touring, then you will see the benefits.
