One of the issues with finding a way to run a set of cast wheels on the S10, beyond simply getting the wheels to fit and aligning the brake rotor, is the ABS type we use. You additionally need to either find a wheel set up for the same type of ABS sensor rotor, or machine/adapt a wheel that fits to use the ABS sensor rotor that works with the Super Ten and make a sensor cover to fit and work with the correct placement of the pick up sensor.
That was the appeal of the FJR wheel, some Gens use the same system of sensor rotor and cover as the Super Tenere. Sadly, that wheel won't work w/o extensive machining and either welding in new material or press fitting a sleeve with a new piece that fits with the Super Ten dimensions. And its still speculation on if you will end up with a wheel that can be directly swapped out. It would be great if Yamaha simply offered cast wheels as an option or another bike's wheels were a direct fit, but as far as I know that isn't the case at this time.
