there must be some high output, low rev alternators / generators out there
that can do the job.


High output and low revs just don't go together. Halving the rpm tends
to double the size and weight. There is a reason why they invented
gearing. I think maybe you need a big prop and a gearbox.


Changing drive pulley size can improve alternator output a lot more
easily than props and gear boxes. Another strategy is to install a
high output alternator and run it at a reduced rating that still meets
your needs.
