I would say you can't do this.

In 2-slot addressing mode, the pair of modules at the same logical address (2 physical slots) would have to be "complementary", i.e. one is inputs only, the other outputs only.

Since the SDN is both In and Out, it will have to have its own unique I/O space, so you can't partner it with any other module.
