Engines are tested with 8 pound birds so I doubt it. Most of the fan blades may go through the bypass and not damage the power turbine so likely only a loss of power from vibration of main fan blade and no damage to compressor blades. Though your scenario is possible (random odds on this), even the turbine can injest a few blades and keep running, but then the power would be real low.
