Very unlikely. We are where we are today because along the way there were a LOT of alternative theories considered and discarded, either because they did not agree with experiment, or because they lacked explanatory power. Science is actually very open to new ideas. We even know for certain that the current foundations WILL change (because dark matter, etc.) It's just that making progress is really hard because our current theories already account for ALL of the phenomena that are easily accessible here on earth.
