No, and this isn't something that is going to be available, at least not in the short term. The next major version of Help+Manual will allow you to mix portrait and landscape pages, but the same paper size throughout will be an absolute requirement there as well.
If not, do you have a suggested or recommended approach to achieving a single PDF manual [preferably] that has content in both A4 and A3 page sizes?
The only suggestion I can make there is multiple PDFs, with file links to the larger ones. Unfortunately, the PDF format is still really bad at handling links and once a user follows a link to another file there is no way back to the original file. Frankly, PDF is still the worst format in the world for interactive content. It should only be used for printing (it is really just raw printer output in a file, displayed with a printer driver that prints to the screen instead of to paper) or for users who want to read something from beginning to end sequentially. If you want interactivity, use WebHelp.
Also, for CAD DWG / DWF files, what might be the best way of getting them into my H&M projects?
The best option would be SVG, if you can convert them to that, as that is now natively supported in Help+Manual 7. Otherwise I would suggest screenshots, and then insert them as normal bitmap graphics.
