@Quoth Thanks for the research.

It will result in a huge table compared to proofed full OCR and a subsetted Unicode characterset, but will work with no training and any font/alphabet.
Quality is poor compared to human proofed OCR or a decent scan, but worked on the 167 dpi 6" viziplex 4 level screen on K1.
So the only viable conversion is to an image /TIFF/PDF image (calibre won't do it). Then the image might be OCRed.

Yep.

"The Tool" can
apparently assuredly remove topaz drm, but the Calibre plugin then converts the file to HTLMZ and does not preserve the AZW1 format.

Correct, the scrable plugin only accept AZW3 EPUB and KEPUB.
