Layout and Design Question

I’m beginning to play around with laying out a group of articles from North Dakota Quarterly on World War I. I’m committed to using Doves Type for all sorts of reasons ranging from the peaceful name to the vintage feel and the story, of course, of its rediscovery.  

At the same time, I’m trying figure out how best to lay out the page. Doves lacks italics or bolds, so everything has to be done with the text itself (and, say, small caps). I like that as a challenge and find that it is a fairly easy limit to overcome.

Below are a few page mock ups.

Larger (12 pt font) and in a single text block:

Or in columns with a smaller, slightly denser font spacing?

Any feedback would be great!
