Archimedes' Principle and Gravity

This blog has represented gravity as a type of electron buoyancy. Of course the effect of all of the electrons on the nucleus-es is considered. Assuming Archimedes' principle to be formulated as Wikipedia has as follows: observed weight = mass - displaced mass.

Is it possible to develop a similar relationship for the gravitational relationship between large mass and the electrons escaping a mass the size of a planet. There is a propensity for electrons to escape the center of mass due to the excess negative charge found there in any mass. Permeating the mass is the propensity for negative charge to want to move out from the center of mass. Charge balance brings electrons and with it mass back towards the center of mass in what we call gravity.

Observed weight = pressure due to charge balance return to the center of mass - pressure of electrons moving towards the periphery of mass. There are differences between gravity and Archimedes' buoyancy however they are analogous. Buoyancy involves atoms of different sizes displacing each other while gravity involves different parts of the atomic structure displacing each other to cause movement of a mass.
