This question is from 2012, but I think this is a relevant/interesting issue. In my opinion, I always take a profile more seriously when I see that someone has made the effort to include a bio and/or text of or links to original documents related to the person.
If you find someone's will, I think, at minimum, you should provide enough source information so that a person could find the document.
For wills that are a few pages, I will usually type them into the biography. For longer documents (like probate files or Civil War pension files), I will typically just either provide an image and/or text of the part of the document that has significant information (for example - pension files often have marriage records, for example).
Here is one of my favorites, my profile for my gr-gr-gr-gr-gr-grandfather, Reuben Lothridge, whose will is probably the most important genealogical document I have found for him, since it is the only source I have seen on the names of all of his children (and the only direct evidence that he is the father of my gr-gr-gr-gr-grandmother):
