Given your use case you can check this plugin Microsoft Document Editor . Using this you can have the users edit a word document from within Appian itself and once they are done then export that doc to pdf by using pdf tool plugin.
I personally have not explored the Microsoft document editor plugin but given your use case it might suit it very well.
