Can I come up with a new theory in the course of my PhD research? [on hold]

I have reviewed the theoretical trajectory of my research topic and I see gaps that I would like to fill with my own proposed theory. Is it too early in my career to put forward a theory? I am just a PhD student. If I can put forth a theory at this stage, what is the best way to go about it? Will the fact that I am a junior faculty member and a student affect the reception of my theory in the international scholarship community?
