Yeah, that should work.

I thought "svnobliterate" / "svnadmin obliterate" was a concept that
had been proposed but that nothing had been implemented yet.
If you want to throw away the history of the first, say, 1000
revisions, you should be able to use "svnadmin dump" to dump
revisions 1001 thru HEAD, then move your repository out of the way,
then create a new repo, then load in the dumpfile. However, I believe
this will renumber your revisions, so all existing working copies
will become unusable and you will need to throw them away and check
out new working copies. Also, if the files that were in the first
1000 revisions are still around in the repository today, then getting
rid of the first 1000 revisions may not help you save any space. You
could try it out as a test -- just dump recent revisions, load them
into a new repository, and see if it's any smaller.
