This is essentially what the philosopher of science Paul Feyerabend did in his provocative 1975 book Against Method. Feyerabend argued that the great scientists of history did not follow any single, codifiable method of discovery, and that rigidly enforcing any one scientific method would have caused major advances to be missed. Galileo, for instance, made his most important breakthroughs precisely by violating the methodological rules that constituted the science of his day. Feyerabend articulated a meta-theory of scientific progress: The only rule that holds across all of its history is that there are no fixed rules.
