Not for golden age or Silver Age, certainly not for Silver Age because it's an actual (dead) religion.
Heros from that age all have to have names you can pronounce at a glance.
Here's an expansion on >>6414522 idea of Sinistroids, instead of being robots, let's make them energy constructs created by The Sinistar from his own energy.
And it's this that gives some ancient but slowly dying race the idea of forming their Not-Green Lanterns.
All of the Rings/Belts/whatever's draw their power directly from the Torso to create their energy constructs, and you now how normally in these cases, the user is advised to only use their powers in the line of duty or somesuch? Not in this case, use it to make a house, do your chores, move rain clouds away, take joyrides through the universe, because no matter what: the less energy the Chest has at any one time the better, just in case The Sinistar manages to steal it back.
When he's awake, using the Rings/Whatevers power on him would require the user to make a will check vs Sinistars (which is godly as you would expect)
One person probably couldn't manage it... 20, 30, a 100? Those are slightly better odds...
Of course he's going to be killing them in large swathes as their trying to put him down, so in the end it might be down to one last NotLantern who perhaps get's a lucky strike in when Cro-Magnon Man or a Superman aggregate pops up and distracts Sinistar.
Nah, don't have him wake up as early as the golden age. Foreshadow the fuck out of him right the way through the Golden and Silver Age, it should be a big, possibly end of everything event.
I like the general scenario though.
