How about making the subset of the svn repo configurable using
something like include/exclude rules? This would allow one to extract
relevant subsets of a big svn repo. I have had to works with some
hugely sprawling svn repos that prohibit being cloned with
hgsubversion today. And I can imagine there are more of this since
with svn's approach the sprawl is not big issue (and has its
advantages).
