Here's an idea that I have in mind:
on a well established blog that you own but can't be bothered to blog anymore to it, my idea is to have the home page divide into sections that are sponsored by gurus in the niche.
So it could could be an idea to ask a number of gurus to provide some content such as their portrait and blurb followed by a link to their sales page tagged with your affiliate link.
Then, at the end of the page, have your own email list subscribe form and offer to let the subscribers in on the discounted offers etc. (stuff that you negotiated with your guru friends).
Just some initial thoughts on how to re-purpose a blog.
