Oh, I see. You're thinking of a versioned property, like what's used
in the text-time branch. Yes, if you wrapped both commit/import and
update/checkout to do the right thing in either direction, it sounds
like that could work.

I was thinking of an unversioned property, specifically the svn:date
property of the revision, of which there's of course just one for the
entire revision. If you check in (or import) multiple files in a
single revision, they all have the same svn:date.
