Yes.

I'm right in the middle of writing a script that does that.

I will use
    mkdir -p path1 path2 ...
    svn export -r<revision> file1 path1/
    svn export -r<revision> file2 path2/
    ...
instead. I don't want to spend years waiting for complete checkouts :)

My initial question was if there was a quick hack that would enable me
to use one of the scripts (like tl-update-containers) to do the same
as you describe above, but if there is nothing ready-to-be-used, it
will take me less time to write my own script than to understand what
is going on it TL scripts and modify them. And my code is almost
finished now.
