I guess the only thing I wouldn't want to do is have the alternator and DC/DC converter BOTH running. They might not like each other that much.
If you had two large power diodes that were rated high enough then you could isolate the dc/dc converter from the alternator and whatever one was putting out a higher voltage would charge the battery, that seems like the simplest solution if you want an alternator, is there a problem with not having an alternator and just running all of the electrical loads off of the drive pack? still having a battery that the DC/DC converter kept charged, for starting the diesel engine, but once the engine started the drive pack would recharge that starting battery.
