I think that is a good idea, but I would wait a few weeks.

I am right in the middle of a refactoring of the Dockerfiles to take
advantage of the new(ish) Docker multi-stage build functionality.

I think it would make more sense (and be still easier) for your
"testing" image(s) to build on that base instead of the current
Dockerfiles.

I need, for the TIER program, to create images that use CentOS 7 as a
base instead of Debian.

I don't have a full technical solution yet, but I expect that will be a
parallel multi-stage Dockerfile. 

The goal of course is to have one maintainable set of files with no
overlap so that I am following the DRY prinicple. Unfortunately there
are still a few pieces of Docker functionality missing that make that
really easy.

I am not so sure. I don't think the base OS will matter at all. I think
it is more important to have more tests against one "platform" than
tests against multiple platforms.

Yes, in a few weeks. 

In the meantime just do whatever is fast and easy to let you make
progress now, realizing you might have to throw away any Docker changes.

Let me think about the best way to do this...

I will.
