Relayering the onion for PDF reversal from ODG to Scribus

 You can make a layered PDF from a LibreOffice drawing, at least obliquely.

Exporting to PDF from LO does not capture the layers in the source as PDG 1.6 layers.

Opening with Scribus, then exporting to a layered PDF works. But. The layers go from left-to-right as top-to-bottom, rather than right-to-left. Later added layers end up on top, and if they are a scanned image, everything below gets masked.

Just a little line cut and pasts. Viola!
