No, I don't think this is possible. We have "--full-diff", which
disconnects the path-limiting from the diff generation, so that:

  git log --full-diff --name-status some/dir

would choose only commits for some/dir, but show the full diff of each
commit.

However, what you are asking is to disconnect the two diff options: one
verbose option only for interesting parts of the diff, and then a
more sparse option for the rest. I'm pretty sure the diff machinery does
not currently understand such an option.

It would not be impossible to implement, I think, but I suspect it would
involve refactoring the format selection in the diff code quite a bit.
In the meantime, one thing you can do is generate the full diff output
and then post-process it to collapse the uninteresting bits.  I haven't
tried, but you can probably do something like this using "folds" in your
editor (e.g., shrink all of the diff content for a file to a single
line, but then expand it on demand).
