git-svn is there a way to track non standard layouts?

I've got a directory layout looking like this:
A/{trunk,server}
B/{trunk,server}
C/{trunk,server}

Where A,B,C are small variations of the same project (adjusted to
different customers).

Can I tell git-svn to track those 6 directories or do I have to change
the svn layout to

A/{trunk,branches/server}
B/{trunk,branches/server}
C/{trunk,branches/server}

and use git-svn clone 3 times?
