Journals should not be given the power to implicitly decide what research gets done and conversely they will never accept to be forced to publish all results because of the vast amount of research that goes nowhere.

The whole value for a journal is to be able to select once the results are known because that's how you build prestige.

All you are doing in effect is to lay out a good case why journals should and probably will simply die because this level of transparency would be a great thing to have but is incompatible with the publishers model.
