I forgot to mention something:

Inside the Twist-Lok cans are two phenolic insulators with a thick rubber insulator in between. The terminals go through one phenolic insulator, the wire leads go through the other one (and through the rubber insulator as well).

You may be wondering how do I have enough lip left on the can to be able to crimp it over again?

Simple - eliminate the rubber insulator and you have enough aluminum "lip" left to recrimp the can.
