This is already essentially how it works. A new theory has to be complementary to old ones. This is often said in terms of “matching the predictions of...” another theory. There are more standards of course, but that’s the baseline. A lot of pet theories people have for things like QM fall apart because they don’t match the tested predictions of QM. For example, Special and General Relativity make new and more accurate predictions which complement, but do not contradict Newtonian theory. An issue with a theory replacing QM for example, other than the high degree of precision needed, is Bell’s Theorem, which tends to rule out LHV theories. https://en.m.wikipedia.org/wiki/Bell%27s_theorem https://en.m.wikipedia.org/wiki/Bell%27s_theorem
