Does this ever happen?
p + [itex]\gamma[/itex] [itex]\rightarrow[/itex] n + e^{+} + [itex]\nu_e[/itex] It seems possible, if the [itex]\gamma[/itex] has enough energy, but I wonder if anyone can confirm that it happens.

p + gamma > p + e+ + e then, electron capture. Combine, and you get the proposed reaction. This supports the view that there shouldn't be anything fundamental prohibiting this.

Thank you. This does indeed make it seem even more plausible.
