I think that would be an exercise in futility. Besides, why would you want to use or risk an expensive, fine device to flatten a cheap stone?
The DMT D8C is a good, inexpensive flattener. Amongst knife geeks ( ) the D8XX is regarded as the most aggresive cutting tool around, but it's a little too coarse to take to your finest stones.
Once you have your stones flat, you shouldn't have to worry about them for awhile. Knives lose a lot of metal during sharpening, so the stones will dish, but razor honing is a far more gentle process.
