Not that I knew of, but theoretically feasible. In fact I was working on
something like that once, but it means loading and parsing two dumpfiles,
sorting them by their commit date, adjusting paths, mapping revision numbers
between old and new repositories and possibly a whole slew of other problems
I haven't encountered yet.
It's not the fact that I gave up because of the task, but I lost interest as a
half as good solution was good enough for us at work. If there is interest, I
can supply you with the half-finished C++ code though.

I'll attach a file which I used to do the same for our similar task, with the
diff that we migrated from VSS to SVN. The disadvantages are that the
commit-date is not preserved and it requires setting up some hooks for
changing revision properties first. This simple hack works by extracting a
configurable set of revisions and, using svn_load_dirs, puts them into the
target repository.

For us, it was good enough - YMMV and no guarantees.
