Nut dropped into timing chain chasm!

Well... here's how it happened.

I was replacing two stripped nuts on the valve cover of an '85 300D. I got the nuts off and removed the valve cover to replace the bolts. In the process of attempting to remove one of the bolts (using two nuts), one of the nuts I was using slipped from my hand and disappeared into the deep chasm at the timing chain.

I have tried using a scoping magnet, but it apparently it doesn't reach deep enough. I can't see into the area that I need to access, and due to the amount of metal in an engine (go figure!). whatever I use to fish the nut out needs to be rigid. I'm thinking a coathanger with a magnet on the end. ANy other ideas?
