Eric, regarding me being fixed on electron remaining between the two nuclei as the only reasonable explanation for hypothetical fusion in 1000K, so we had 260 posts in this thread and I honestly haven't seen any other reasonable explanation here (?)
I proposed one that has nothing to do with fusion: induced decay/fission. You didn't like it, which is fine. For several reasons I think it's more probable than fusion, even with Gryzinsky to help out with the screening. We can agree to disagree.
Chemistry, charge concentration, screening, topological defects etc. might be sufficient for taking two nuclei to picometer distance ... but fusion requires thousand times smaller distance, and so thousand times larger energy (V ~ 1/r).
You keep on seeking to connect electron screening with fusion. Now that you're fixated on fusion, you're on your own. I suggest that there's nothing on this worldly plane of existence apart from a neutral particle theory such as that of Bill Collis that will bring two nuclei sufficiently close to fuse at rates commensurate with LENR excess heat results. Perhaps you disagree. I will step back and try to learn from the secondary details that you marshal in support of your proposal.
This is just far beyond such "electron-cloud-related" explanations - it is a completely different energy scale.
The scenario I proposed in connection with induced decay (not fusion) was a dynamic one, one that is difficult to model. I have explained above that the potential energy is already there, in the nucleus, and that what might be needed is a small amount of screening to bring about a very large change, like the small amount of mechanical energy in a gun trigger that fires a bullet, or the small amount of chemical energy in a fuse that sets off a bomb. So the energy of the electrons is not an immediate consideration. What is a consideration is how much an electron fluid could under dynamic conditions impinge upon the Coulomb barrier of lattice sites out at the far edge of a topological defect. If you argue that this is impossible, I'll reply that dynamic modeling of solid state systems is hard.
