This is much easier said than done. Let's imagine that, for instance, the way to have gravity comport with the uncertainty principle starts with verifying the graviton doesn't exist, and that gravity is a non-discrete field effect (contrary to electric fields -- this is unlikely to be true or to help, but is an example of a statement we can evaluate for electric fields, which are similar but better understood). The experimental accuracy you would need for this is astounding, perhaps impossible except at exceptionally low temperatures or other extreme conditions.
