Juan Molina: "Try to add a flag to the match procedure in which the non-matched sources are added as additional ‘rows’ in the final catalog file. But at the same moment keeping the useful information from the two original catalogs (i.e., by adding new columns to the new catalog file). The objects with no information in some columns may have assigned a “nan” value."

This is a very useful suggestion to allow users to ask Match to build a combined table that is larger than the two individual inputs. This allows building up of a large collection of catalogs where some rows match and some don't, but all will be kept.
