HR-V with a cvt gearbox

I have a 1998 Honda HR-V JS4 that has a CVT gearbox. This has a severe judder when pulling away. I have been through all the recommended remedies eg. flushing and new fluids, the dealers offered a start clutch, expensive, and went on to say that this may or may not cure it!
Does anyone know if you can fit a gearbox from say a civic or other honda model that is not a CVT. Would like to stick with Auto box.
