Well, I'd go with two separate sensors altogether.  It's almost
always the case that some cylinders run leaner and some richer,
due to all the variables in the intake tract on through, so I'd
be happier if I knew that one whole side wasn't going too lean
when I got on the gas.

It's probably also the case that the relative leaness of the
banks changes as RPMs change, due to intake design, so you need
two separate signals to see when they go up and down wrt each other.
