You can probably

(with-temp-buffer (setq default-directory DIR) (hack-dir-local-variables))
   ...)

Won't that work? I use this ocasionally for my personal horrible ad-hoc
project  managing code (that I hope to replace with project.el eventually).

What happens by default when a user sets other dir-local variables in
her init file? I'd be happy with that ending.

I'd prefer that .dir-locals is used if you can manage it. I don't want to
have to debug other sources of variable settings other than the ones
I have to know now. It also makes backend writing much easier.
