it could be done in Aluminum, Cast Iron was the casting metal of choice for most things casted back when this was made. They cast all sorts of gear boxes out of aluminum nowdays.
With a vertical mill and the old box as a pattern, and a big hunk of Aluminum you could mill out a nice shiny new one in probably less time then it would take to make a pattern and core box then get the thing poured and machined out.
Hard to tell from the photos but if it fits on the mill like it should, a person could take it and heat it up hot enough to burn all the oil and grease out of the metal and relieve any stresses, and with the inside of the crack already Vee'd out prio to heating weld the inside up with some NiCast rod .
that's the X axis feed screw, I'd say its more likely damaged by someone putting a lifting strap where it shouldn't of been
