Is it possible to reconfigure a 48v forklift battery bank temporarily to charge with 24v charger?
You could charge first the half bank and then the other half bank. No problem at all. 

Since the solution is trivial and it didn't came immediately to you, I have a reason to think that you don't know too much about electrical engineering. Well the forklift battery can be lethal in case of short circuit, so I would suggest you to find somebody that has  at least some knowledge.
