When your engine rotates at maximum rpm (10 000), your alternator rotates at more than 19 000 rpm, because it is driven by a chain with 28 to 16 teeth sprokets. Increasing this ratio would need to change the sprokets. The frequency of the magnetic fluxes changes in the stator would go very high, creating more losses in the iron and lower the power conversion factor. The stater, on the same shaft, would drive the engine more slowly when starting, making start more difficult. I think that, though it could be done, it's not a good idea.
