Swapped: Luke Cage & Booster Gold

What if Marvel & DC Comics traded their characters Luke Cage (born Carl Lucas)
& Boster Gold (Michael Jon Carter) and place them in each of their respective
comic book imprints/universes in 1994 after the entire Zero Hour mini-series
was completed?

What would happen if Marvel retconned Cage as a Marvel comic character
with no memory of his original universe and vice versa with Booster?

How different do you think those two chars' origins will be if
The Big Two had made miniseries that presented their
rewritten backstories?

How much would things change for and/with Luke & B. Gold's
allies, associates, enemies, friends, lovers and locations if
they were apart of the swapped heroes' lives?

Finally, how will this trade off effect comicdom, comic companies and anything else?
