Did you ever look into Yoshiaki Arata’s pycnodeuterium?

This sounds very similar.

'Fraid not. You've obviously been spending a lot more time on all the different approaches than I.

The difference between Arata's work and what I proposed and the reference in this thread appears to be the formation of the deuterated layer on the metal by codeposition by electrolysis and then placement of the formed layered metal in a deuterium gas atmosphere and heating it.
