Maybe "Nat Lampoon" did this twice, BUT I recall a DEADMAN with a different origin. A wealthy,bored and insocient playboy accidentally drove off a cliff in avoiding a family having a picnic. The body was obtained by the stereotypical German scientist who once worked in a concentration camp on the executed. He embalmed the corpse, and then died in a tremendous explosion as 2 chemicals "renewed their mutual animosity". A pair of policemen got ahold of the body,dressed it in a superhero outfit - and the story proceeded as you described it.
The artist was Neal Adams. Nat Lampoon is no longer published.
