There is a problem here that you do not seem to recognize. If any meta-level approach is better, i.e., will yield a more correct model of the universe than the current scientific method, then the scientific method will, over time, devour it, make it a part of itself. This is, because in the end, the "better" alternative approach will at some point yield a theory, no matter how small, but still, perceptibly better prediction. It may not do so for QM - it may yield only a different "interpretation", but it will, somewhere along the line, make an indisputably better theory, one that has to compete with theories that could not have been discovered without it, and people will start using it.

In essence: if it beats the scientific method in its own game, it will become mainstream scientific method.
