You would probably know, as long as I have a mallard duck pair on the pond will I not get a wood duck pair to join them? I know people wait many years to get wood ducks and my pond is a long shot due to activity around it (and my dog who can't get too near it but the fence does allow him in the vicinity), but I also wondered in a small pond how a mallard pair and a wood duck pair would get along?
The female mallard is on the nest (somewhere) and the male sleeps in the shade or swims in circles in the middle of the pond every day waiting for her.
I think mallards and woodies do fine on the same pond. I see them (and other ducks) intermix while cruising around our pond frequently. You could always put up a mallard nesting tube, in addition to the wood duck box.
Below are blue wing teal and Canadian geese, hanging out..
