You could install a simple
differential. The required bevel gears may be recovered from old angle grinders.
that is a good idea. there could be 2 versions. minimal version with compensating gear made of angle grinders. version 2 with car batteries and hub motor

Have you driven forklift truck?
Rear wheel steering at speed will be "interesting"
Good luck

Interesting for sure, but real problems occur only if you have a negative caster angle.
