Personally, I think it would had been the other way around. To make Superman rise in those times, using all the Silver age elements, pretty much worn out by the repetitive abuse, you would had need a genious like Alan Moore with a more rekindle vision to reenchant the franchise. (Moore did it later in Supreme, but that is another story). But the spirit of those times was not with those ideas and to force them once and again only would had keep Superman froze. Was Byrne changes the best option? No I think it was not, but it was a departure of what was and that also gave the chance to reexaminate the Silver age elements and put them under a different light.
