Hawkman and Hawkwoman did not get together because they had the same powers. On Thanagar, everyone has those powers, so it's nothing special. Tula and Tempest are together because they trained at the same academy, not because they acquired similar skills at said academy.

Aquaman and Mera do not have any powers in common except those that are natural to them. Batman, Nightwing etc. have no powers at all. All of these people came together for reasons unrelated to their power sets.
