Following up on Eric’s groundwork, I was able to successfully refill cartridges that were scavenged from the disposable Lantus Solostar empties that I had accumulated.  
The cartridges that were scavenged from the Levemir pens would not work, however, as they are just a bit too long to fit into the pen body correctly.  
Now I just have to make sure I never need more than 30 units of Lantus per dose!
