Which part?
If I could go back in time and steal Mike Carlin's job, I probably still would have brought Superman back to life. He gets a pass, because he's Jesus. I would, however, mandate the term "super-resurrection."
But if I could go back in time and steal Dan DiDio's job, I'd have never brought back, or permitted the return of, Hal Jordan (as contrasted to, importantly, the Green Lantern Corps itself), Barry Allen, Ollie Queen, Bruce Wayne (I know, he wasn't really dead), or Ted Kord. Or anybody.
Except, maybe, I might've, but only on the condition that all of them were reclaimed in Blackest Night. That would've been pretty epic, and not the faux epic creation myth that even Johns has admitted was a bit of a mistake.
If we consider the relaunch as a hard reboot, I have no principled objection to Ollie Queen, etc., being alive again. I only have my preferences there.
As for the old fart preference, I'm a little less serious about that. Any character, or just about any character, is capable of being written in an interesting manner. I might prefer narratives about old people who long for the release of death (my taste in novels and films runs in that direction, too), but that's only because I'm a pessimistic dude.
I wasn't very serious about my Green Arrow/Red Arrow pitch. Or was I? The first chapter could be called "Samsara & Smack."
