A few years later, however I can confirm that this works. Ghostcript has been around for around 20 years to my knowledge, although I would like to know exactly what it does when it recreates a PDF?
I has also tried to convert some Apple Preview non-searchable PDF's to PDFA in Acrobat Professional preflight/standards. This did not work for my original text PDF, although it worked for the Ghostscript processed PDF. This suggests that Ghostscript repaired, or at least stnstandarised the PDF, in some way.
Overall, unless I find that Ghostscript reduces the quality of PDF's, this appears to be an excellent solution.
