This is definitely an interesting argument. I'm agnostic at this point as to whether Rossi has used a radioactive catalyst in the past. I suspect he does not now, for the regulatory reasons you mention below.
About the H2 pressure and the mean free path of monoatomic hydrogen -- I'm curious whether you've seen anything on the pressure in the E-Cat. I got the impression along the way, probably from reading unrelated experimental writeups, that the pressure need not be above ambient pressure, and that the main thing additional pressure would accomplish would be to make additional p (or d) available to the reaction sites.
