Retrospective wall ties

I'm reluctant to try to hang a double glazed door into this without tying the two skins together for strength. What's the best way to proceed? Or am i being over cautious?

I used some when I made a window opening into a door. They were a stainless rod, threaded with rubber on. When you tightened a nut onto the thread it pulled the rubber tight and expanded it.

I wouldn't bother.
