Is it possible? i know you can do it with analog amp meters but how would you make an analog voltage meter read a divided portion of that given load, eg. give it 500 and it read 100, or have it read 250.

I think he wanted to drop the scale down and not up.
You probably have to take it apart and take out the resistor and replace it with one of the appropriate resistance. You will need to know the current needed for a full-scale deflection without the series resistor. Then, you need to determine what value of R will turn your desired full-scale voltage into that amount of current.
