Sure.  Gecko has had privileged-stylesheet-only CSS for a while now.

We could.

I think, however, we have a different philosophy about whether apps
ought to appear native.  I think native appearance is a good thing;
it makes controls look like what users expect them to be on the
platform they're on, rather than showing users controls designed to
match the platform the page author happens to like and making users
learn recognize multiple UI patterns when one would do.  I think
it's good that pages appear native in different ways on different
browsers -- I see it as a part of what's now called responsive
design.

If we went with a fixed set, I'd prefer to use a set from the
default theme of some relatively recent Windows version, given that
the colors defined in CSS actually come from a Windows API.  (See my
earlier messages in this thread about my previous proposals to
improve the set.)
