After Lemar's death in the Falcon & the Winter Soldier show, I am kind of interested in what happened to him in 616!
There could even be a sub-plot about some lingering side-effects from the Power Broker treatments that could involve other Power Broker alums, including John Walker, but also Sharon Ventura/Ms. Marvel/She-Thing, Dennis Dunphy/Demolition Man or Antonio Rodriguez/Armadillo.
(It doesn't even have to be the treatment failing, it could be that the Power Broker, or some other nogoodnik, has deliberately dosed those affected by the Power Broker treatment causing it to break down, so that these people will have to do their bidding to get a cure! Bang! Bunch super-pawns, who have to do what you say if they don't want to die!)
Also be kinda funny to find out some deep cut retcontinuity, like that the Power Broker process was reverse-engineered from cell and blood samples taken from Mary MacPherran/Titania, and is a degraded version of whatever process Dr. Doom used in Secret Wars to empower her, making all of them sort of cheap knockoffs of Dooms superior work empowering Titania!
