How can I repair pdf-to-epub conversions?

Some pdfs only show blank pages on the Kindle, so I'm trying to convert from pdf to epub and eventually to mobi. This one's a simple pdf with a good text layer and only 1 image. And 1 column.

Different conversion software has different bugs.

So the original pdf has the best text layer, and the Calibre epub has the best cover, but the Calibre epub has p breaks between every few lines, with erratic spacing, while the other epubs have chapter breaks between every 2 pages, and erratic font-size changes, and probably ocr errors.

I can't find and remove all the p-breaks, or I'd remove the necessary ones along with the extra ones.

I'm not sure how to overwrite a bad text layer with a good one.

I can't open all 3 epubs at the same time in case I want to splice together 1 epub with the best sections from all 3.

P.S. The original pdf was left-justified, rather than double-justified, so most lines triggered line-unwrapping. The original pdf has tabs at the beginning of each paragraph.
