LCD drivers

I am considering using an MCU that has built in LCD drivers, but it only
implements 1:8 multiplexing. In other words, it has eight "common"
lines that are sequentially asserted. I need to connect it to an eight
character seven segment display. None of the displays that I have found
are designed for 1:8 multiplexing. Is it possible, and reasonable, to
use this MCU with a display that only has four commons (1:4
multiplexing)? If so, would I use four consecutive commons, or every
other one? Would the appearance suffer in any way? And what if the
display is 1:3?

Thanks for any help.
