The CRIS adapter is probably the smoothest way to go. Buy it, put the cells in it, and drop it in. That's easy, and your meter will have the correct voltage.

Thus, the EASIEST solution is not to even worry about the meter and either use your best guess or calculate exposure externally...both of which are faster than using the meter in the camera!
