Atomic Nucleus: Coulomb without Strong Force

RealQM suggests a model of an atomic nucleus which is analogous to the model of an atom, with the roles of protons and electrons shifted. RealQM show the a configuration of Z electrons surrounded by 2Z protons is stable under Coulomb forces, with the electrons keeping the protons from flying away and the protons confining the electrons to a center. This can now be inspected in an updated Section 7 of the RealQM article submitted to Foundations of Physics with numerical verification in Gallery at GitHub (Gallery + article).  

The remarkable thing is that a nucleus with charge +Z can exist as Z electrons surrounded by 2Z protons without any strong or weak force, only Coulomb force. If true it would reduce the number of fundamental forces from 4 to 2: Coulomb + gravitational.
