I'm sure you could do something very similar, although I don't know
if the SVK data chunk (base64-encoded, flate compressed, text data)
would map cleanly to plain Subversion. Unfortunately, I can't find
any real documentation on the chunk format, and my Perl-fu skills
aren't up to the SVK source...

Aside from that, SVK patches are just unified diffs, so at the very
least you can come up with additional Subversion-specific data
chunks that are ignored by patch(1) and SVK, at least initially.
Perhaps some combination of the dump and unified diff formats?
