Considering how turbine engines fitted to aircraft work, with their own generators coupled to them (and in some applications an all-electric starter-generator instead of the pneumatic starter separated from the generator which became mainstream in large commercial aircraft), the idea of a turbocharger-driven alternator doesn't seem so unconceivable at all. I'm sure upcoming advances in the usage of materials with greater thermal insulation properties such as ceramic compounds are likely to decrease the possibility of heat damage to the magnets.
