One 50Mv 500A shunt, two ammeters?
I've already got a Deltec 500a 50Mv shunt wired into my system for my battery monitor. The issue is I have a desire to see alternator charging amps when driving and my battery monitor is not safely...

Use the 75 mV meter and make you a little chart that multiplies the meter reading by the scale factor. If you want to get more sophisticated you could have a simple op amp scaling circuit between the shunt and the new meter. If the input impedance of the meter is specified you should get an idea if the additional loading is impacting your 50mV meter. I would be very surprised if there was any effect at all.
