No.
I grew up on the Silver/ Bronze Age.
On a practical level, it would not work today. The readership today is mostly adults, not grade schoolers.
The other reason is that they might *say* it's Pre-Crisis but it would not feel that way to me. For instance, when they were bringing back the alternate realities, they did a series where they published comic from every era. The Post-Crisis one felt like it was Post-Crisis. The Golden Age was cheating a bit but mostly felt Golden Age. However, the so-called Silver Age one, a Legion of Super Heroes story, just felt like a modern comic with something remotely resembling the Legion's Silver Age history, characters moping about their feelings for twenty pages but supposedly in the Silver Age.
"Pre-Crisis" is more than just a set of events. It's an era in our culture, a time that is gone, a style of storytelling that we are not going to see again except in some sort of retro setting like Batman '66, Wonder Woman '77 or the upcoming Superman '78.
Pre-Crisis might work in that sort of context where you publish one comic a month in that setting but it's not going to work as the main setting.
