You can find the engineering drawings here:

I have two of them somewhere in my archives.  Currently lost, but they'll probably turn up again someday.

I think its going to be hard to modify an existing connector.  You might be able to make a PCB of the right thickness and wedge it in such that it makes contact with the connector, but  I think there's high risk of screwing something up, and putting too much stress on the connector.


I think Matthias has an interesting idea.  I had an old 30-pin iPod dock connector that had removable spring contacts.  See this picture:

Someone could in theory engineer a housing that takes the contacts from a connector like this.  It would need to be printed on a very high resolution 3D printer.  Doable, but someone would have to care enough to do it right.  Odds are it would take a few iterations before you had a good connector.
