I worked at a publication that used Miller Display for headlines, Miller Text for body copy, and Franklin Gothic for captions, authors, subtitles, etc. In my (unlearnèd) opinion they worked very well together. Also don’t forget all the very nice italics that come along with Miller. You can do a lot just by mixing those into the equation.

do you have some example layouts? or the fonts you’ve chosen so far?
would be a huge help.
