IIUC you want to have a "directory-local" setting for auto-mode-alist,
i.e. some way to specify that "files with name *.foo under this
directory should use bar-mode".

This sounds like an eminently reasonable request, and I don't think you
can do it with .dir-locals.el currently.  So please M-x report-emacs-bug
and request this new feature.
