It would be a very interesting read

Yes, it was, 1/4 century ago when I was researching asteroid mining.

It doesn't help me to understand your understanding of Goddard if you have no references however. If in the literature there is no mention of the things you claim Goddard to have actually performed then all I can deduce from that is that he never did. He may have spoke about such technology or theorized about such technology but nothing I can find has him experimenting with ions.
