I do this quite frequently honestly...sometimes with some relatively complex things that would be a pain to re-create.
A second option is to take the original file and save-as a different/new file name, change the material parameters and delete the objects you don't need, process from there. That's sometimes faster than the other method but both have their benefits.
I agree with the first option. I have to do that a lot when I am messing with other folks projects since my machine is a 6040... very limited, so I have to break up to smaller projects. Copy n' paste to a new project file and try to duplicate the toolpath.
