I know I would need a 24 to12 volt converter to run the electronic
ignition
system and they're easy to find. I'm still a little undecided on what
type
of engine I want, but I need to make up my mind soon.

Some large trucks use 12-volt systems and 24-volt starters.
They have two 12-volt batteries, connected to a series-parallel relay
that makes the connections necessary for starting.
You might be able to work up something similar but opposite. 12
volts for starting, 24 for run. Two smaller 12-volt batteries in the
same rack or box, and a heavy relay to shift things between starting
and running. I can't remember the wiring diagram for the relay, but a
truck shop might have one. I've been away from the industry a long
time now.

If you are using a non-geared starter, with copper windings, it will
take 24 volts and will crank like crazy.
HOWEVER, your local auto electric shop SHOULD be able to get you a 24
volt starter to fit
