Using Ilford multigrade RC papers I have done similar things, but usually with many, many prints, from the one negative.

The biggest run I have had, was just over 2,000 5x8" prints from the one negative.

I printed a handful at slightly different exposures and allowed two days to pass before I developed them. I then compared the results with prints developed straight after exposure, I couldn't see any difference.

That said, there is a difference, especially with the variables Ray pointed out. I cannot explain them rationally, but they are there.

Having done several large print runs from different negatives and papers, I can say it's possible, but I wouldn't do it for single print exposures.
