Is it possible to make global color changes to a multi-page PDF using Acrobat? For instance changing all the type in the document that is colored RGB black to 100% Black?

To reset a document containing only "rich black" text to K-black, in the dialog, select "text" as the object type, "Convert to Profile", select a suitable K-plate profile (such as "Dot gain 10%") and click OK.
You can construct quite complicated profile rules to protect certain elements while altering others - the Acrobat help file has more info.
