  By combining the postulates of macrorealism with Bell locality, we derive a
qualitatively different hybrid inequality that avoids two loopholes that
commonly appear in Leggett-Garg and Bell inequalities. First, locally invasive
measurements can be used, which avoids the "clumsiness" Leggett-Garg inequality
loophole. Second, a single experimental ensemble with fixed analyzer settings
is sampled, which avoids the "disjoint sampling" Bell inequality loophole. The
derived hybrid inequality has the same form as the Clauser-Horne-Shimony-Holt
Bell inequality; however, its quantum violation intriguingly requires weak
measurements. A realistic explanation of an observed violation requires either
the failure of Bell locality, or a preparation-conspiracy of finely tuned and
nonlocally correlated noise. Modern superconducting and optical systems are
poised to implement this test.
