git-svn with non-standard repository layout

Hi,

Is there a way to handle svn repository with following layout?

repo/trunk
repo/branches/branch1
repo/branches/branch2
repo/branches/work/developer1/branch3
repo/branches/work/developer1/branch4
repo/branches/work/developer2/branch5

In default configuration it treats "work" dir as a branch. If I
configure it with branches = branches/work/*/* it recognizes them
correctly, but then the "normal" branch1, branch2 are lost.

Ideally, I'd have one git repo with trunk, branches/{branch1,branch2},
work/developerX/branchY branches...

Any ideas?
