Reread the Squadron Supreme's first appearance a few days ago and recalled how lame DC's take on the same concept was (The Heroes of Angor) DC has revisited the concept a few times with mixed results.
Thought I'd take a stab it by "Marvelizing" some DC characters, using the 1960s Avengers line ups
The Iron Knight- Bruce Wayne. Wayne was injured in a botched kidnapping attempt that killed his parents. Left to die he was found by Dr. Leslie Thompkins and nursed back to health. With Thompkins help he developed various technologies to overcome his injuries. Using these he captured the gang that killed his parents and were terrorizing Thompkins’ neighborhood. Modifying the tech into a suit of combat armor he began fighting crime as the Iron Knight.
The Behemoth- Clark Kent. A reporter, Kent was covering an experiment testing the mysterious K-metal, when he was caught in an explosion trying to rescue his photographer, Jim Olsen. Seemingly unaffected, Kent soon discovered that exposure to sunlight made him taller, stronger and nearly invulnerable. Unfortunately, it also made him more brutish in appearance and looked upon as a monster by the people he would try to aid. Tasked to hunt down this “monster” is General Sam Lane, the father of Lois Lane, the woman Kent loves.
Athena- Diana Prince. While on a remote Greek island conducting a dig, archeologist Diana Prince stumbled upon a temple dedicated to the goddess Athena. After falling through the floor of the temple and twisting her ankle, Prince grabbed a spear to support her weight. By striking the spear to ground, Prince was transformed into the goddess Athena herself.
Blue Jay and Hummingbird- Carter and Sheira Hall. The married couple are ornithologists, biochemists and cyberneticists who discovered an element called Nth-Particles that allows them to shrink to the size of a small bird. They developed a helmet which allows them to communicate with birds and wings that allow them to fly. Hummingbird has a sonic blast built into her wings.
The Guardian- Jim Harper. Harper was America’s greatest hero during World War II. Decades later he was cloned and brought back to life in the modern day by the Cadmus Project.
Green Arrow- Oliver Queen. Queen was a rival of Bruce Wayne who was duped into fighting the Iron Knight by the Black Canary, a member of a criminal gang. Reforming he joined the JA.*
Silver Sorceress- Zatanna Allen. Once a reluctant member of the terrorist Meta Brotherhood the magic welding meta joined the JA to show that not all Metas are to be feared.
Scarlet Streak- Bartholomew Allen. The twin brother of Zatanna, gifted with superspeed and a quick wit. Like his sister a former member of the Meta Brotherhood.
The Privateer- Mark Shaw. A master swordsman, Shaw was secretly working for enemies of the JAs and tried to destroy them from within.
Hildr- A Valkyrie from the Norse myths and a friendly rival of Athena.
The Golden Fox-Mari Macabe. Heir to the throne of the African nation of Zambesi, Macabe possesses an amulet made of Tantu, a metal only found in Zambesi. The amulet grants her various animal like powers.
The Wraith- An artificial lifeform designed by Prof. T O Morrow to defeat the JA, The Wraith turned on Morrow and allied himself with the heroes. The Wraith can turn his body from solid to as thin as air and control it to make mini tornados

In the Avengers' story the Squadron Supreme's archer was also called Hawkeye, so I homaged that here.
