This would be dumb as hell and completely dishonest. It would be trying to create meta where there is none. Because the influence of Watchmen had NOTHING to do with the Death of Superman. The Death of Superman was essentially a joke backup plan that turned out to be lightning in a bottle. Late fall of that year was originally slated to be the wedding of Lois and Clark. But ABC had picked up the then-new Lois & Clark tv show and there was a deal made that the marriage in the comics would coincide with the eventual marriage in the show (which was designed to happen eventually if the show lasted, which it did), so the marriage happening at the end of '92 was a no go. So they needed a new storyline, and while brainstorming someone joked that they should just kill Superman. The joke actually gained some traction and the rest is history. It had nothing to do with the dark nature that 80s stories like DKR and Watchmen inspired. It was a complete happy accident.
(Not meant to be lecturing you the poster, as far as I know you already know this, I was just venting)
