Be careful about how you define those terms, as they may be idiosyncratic. "Rationalism" and "Empiricism" have long philosophical histories, and are typically seen as parallel, not-quite-rival schools of thought, with the rationalists striving to root all knowledge in a priori rational inquiry (Descartes' Meditations is the paradigm example). I'm not sure it's wise to flip that on its head by redefining such a common, well-denoted term.
