Is it just a case of adding transparency in the Scintilla code base which would then be available in QScintilla? Or is it something more tricksy like ensuring the Scintilla code is compatible with Qt’s transparency mechanisms?

You are best asking that on the Scintilla mailing list. Scintilla supports transparency for specific features, but in a strange way (possibly to avoid API incompatibilities). It shouldn't be difficult but it may have to be done in a specific way in order to be accepted. I would make sure it worked properly with Qt.
