Yep. something like the setMarkdown could be a way

Correct.

It is in the convertOpenFile function in that file it is called that all calls
to libdiscount is, iirc.

Okular has a class of generators that just converts input to a QTextDocument.
This is one of them, so it is basically done once a QTextDocument is generated.

I think a first approximation would be to just replace the current one.
