Let say alpha particle overcomed Coulomb repulsion between two protons - this is gigantic force (MeV-scale), doing it with magnetic: Lorentz force is not realistic, would require gigantic velocities and magnetic fields ... in contrast, alpha particle has zero spin and nearly no magnetic field - what is well confirmed e.g. in energy spectrum of helium.
Topological reasons can be used e.g. for charge/spin quantization, but atomic scale is much too large.
Regarding connection between EM and mass, again physics disagrees: there are massive particles without EM (pi0, neutrino), or EM without mass: photon.
ps. I have finally found some downloadable Gryzinski's CF paper "Theory of electron catalyzed fusion in Pd lattice": https://aip.scitation.org/doi/abs/10.1063/1.40688
His lecture: http://www.gryzinski.com/ramkiang.html
Hot fusion overview paper from his group: http://yadda.icm.edu.pl/yadda/…n___energy_for_future.pdf
One (top)/two(bottom) electron trajectories for molecular bonds from his book, top-left is the one which could allow for fusion: with electron traveling between two nuclei, screening their Coulomb repulsion. In the paper above he writes that Pd lattice helps stabilizing such trajectories:
