It's not a patently bad idea, but I dunno, I prefer to live with alternate treatments than this strangely streamlined continuity that DC favors. The thing is, I think these approaches set the companies apart in a very substantial way:
For DC, the particulars of continuity matter, and whenever they come up with a 'preferable treatment' somewhere, it is their preference to integrate into the main continuity to enhance it. Their approach is essentially one of consciously overhauling the state of affairs by swallowing the above par treatments.
For Marvel, continuity is set as an 'at the moment' thing that exists only as a Present State of Truth. In execution, this means continuity becomes revised insofar as it is pertinent to the story. For example, if a recent story says something happened, it essentially only pays attention to whatever past events matter to the story being presently told.
Take the X-Men: Uncanny only acknowledges recent events, and no matter how 'recent' the past is (Scott listened to 80s music, Professor X grew up during the Nixon years or Beast had a swinging 60s past) it becomes negated in a mini that decides to 'retell' the past as either being a recent past or a distant past. They contradict each other, but it doesn't matter.
Peter Parker's generation listened to 'twist' records, survived flower power and his wife was once offered to do a nude scene in a "Schwarzenheimer" action movie. Their coming of age years are essentially fluid, and their marriage has experienced the entirety of the last 3 decades of pop culture.
Functionally speaking, it becomes futile for one to even quibble about continuity in Marvel because The Past becomes an intangible thing shifted and shaped to meet the demands of The Present.
