I was there for the first clone story, the Clone Saga mess, and all the subsequent stories to follow. I still think killing off Ben Reilly was one of Marvel's worst decisions in all the decades of its history. The same goes for bringing back Norman Osborn, but that's another discussion entirely.
I'm not so spry anymore so my memory isn't what it used to be, but is there any room in the 90s Clone Saga or the sequels that allows for the return of the heroic Ben Reilly? Not the guy cloned from (allegedy) Ben's clone remains or the current iteration that's now a villain. Could it be that Norman (ugh) or Miles Warren replaced Ben with another clone before that "final" battle in Peter Parker: Spider-Man 75? I know anything can happen in comics, but I'm wondering how feasible it would be in light of the last few years' worth of stories.
For my part, I'd make it simple: the real Ben has been in cold storage for years, occasionally studied by Warren and then put back in (not unlike Buck as WS). He gets free or is found and is now a man out of time, if only a few "comic book years." He reunites with Peter, is grateful his own life never got that complicated, and heads out to start a new life...again. This time, he's a globe-swinging hero and his book changes setting with every arc. An itinerant Scarlet Spider or maybe he decides on a new name...Web-Man?
No matter his code name, Ben's the hero he was in the old days and his book is the one Spider-Title allowed to be something rare these days: fun.
