It's easy to cherry pick titles and use them to demonstrate either position. I could just as easily point to the first What If series to demonstrate that Marvel wanted to retell the stories they told during the Silver Age, or the Invaders to demonstrate that they wanted to recreate the Golden Age. At the time, I never noticed any disconnect between the Silver and Bronze ages. It just seemed a natural progression from what Marvel did in the sixties, spending more time on characterization and giving the characters mundane problems. The disconnect came sometime later, when DC and Marvel began to write specifically for an older audience. The only way to return to the comics of the sixties through early 80s would be if a large percentage of their audience were 10-15 years old and they took that into account. And maybe if they began working under the old comic code restriction. Maybe a few other things, too.
In short, it's not really possible to recreate what comics were 30 years ago, any attempt is going to both fall short of the mark and not work as comics of the '00s so they shouldn't even try.
