The interesting implication of the Arata-Zhang experiment for this subject, is the extraordinary claimed loading ratio of over 3:1 (deuterons to metal atoms).
But the CFB concept might work as well or better with protium. Compelling evidence has been found for the occurrence of superfluidity in liquid hydrogen since 1995 (McClintock) - there are a half dozen reports of this, but curiously none with deuterium - and actually at least one report with HD. Whether you call it a "molecular boson" or a "fermionic condensate" very cold hydrogen in a matrix would have special properties due to its already high density. At a loading of 3:1 - we seem to have an effective density of hydrogen (atoms per mm^3) an order of magnitude higher than in liquid hydrogen, which could be the most amazing thing about the Arata claim, if real. What does this do to the possibility of a waveform overlap? Of course, one might opine that "Catch-22" you cannot get to that degree of loading when you are near absolute zero, since the fusion will have already started! Jones
