it's a little weird but go with me
I would give Duke Thomas two things, a black Signal version of his bulletproof We are Robin jacket (I loved that Duke's Robin set-up) and a reflective Nth metal mask what bolsters his photokinetic vision and allows him to see into people's heart like the Batman Who Laugh's visor; and all that other cool stat boosts that Hawkman says come with Nth Metal use. something reminiscent of Looking Glass.
Batman training, daredevil-esque senses, psuedo-empath abilities, and Cap level stats? that's a solid upper tier street-leveler and with his boosted photokinesis a possible Kryptonian fail-safe.
