Thanks for the challenge. (Seriously.) I don't want to add pain to
myself and others needlessly. :-)

I think these are great points. And if it were up to me, I can imagine
this would be a better approach in many respects.
But alas, this is for a project that I don't control. They've chosen
docker, and I'm trying to fit a FreeBSD option in among the mix as
painlessly as possible (for them). The fuller details are here, if
you're interested. 
(Indeed, I don't think this problem really requires virtualization at
all. It's just that nobody has solved my problem in a portable
language yet. The Java software , which I'm using indirectly from
the Clojure software , doesn't solve the problem directly but
instead uses JNA  to effectively shell out to a library, libsass.so
That said, if one did create such a monstrosity as a docker image
containing a KVM hypervisor containing a FreeBSD VM—and figured out
how to pass commands and mount volumes from docker -> FreeBSD via
KVM—that could be a nice "evangelism" move to give the masses who use
docker a cheap and easy way to try out FreeBSD. Plus, such an image
could be used to provide FreeBSD support for other software as well.
Maybe I'll add that to my "one of these days" list...
