So, can the presence of this 1% of plasma be detected ?

Yes in the form of synchroton radiation. But there lies the weakness in the Peratt's galaxy forming model through Birkeland currents.
Synchroton radiation extends into the radio wave spectrum. Therefore galaxies formed through this mechanism should be able to emit radio waves.
Radio wave emissions however are an exclusive property of elliptical galaxies.
