This lets you keep Ede from Lonesome Road and re-enter the divide with him.

SPOILER WARNING:This file, when added in after you defeat Ulysses, will allow Ed-e to survive cancelling the missile launch. It will also let you keep him as a companion. Thereafter you will find that you can enter and leave the divide at will with him. The Lonesome Road Ed-e does not count toward your number of companions so you can enter any dlc area with him. Also note that the newest version of the file allows you to dismiss this Ed-e and he will return to the Lucky 38 player suite rather than the divide. And yes, as has been asked, this will let you have the Lonesome Road Ed-e and the Prim Ed-e as companions both at the same time, as well as a humanoid companion.
Note you should wait to add this until just after you defeat Ulysses to load the mod. I have mine added last in the load order and it always works - I don't know that it matters where it is however.
Note that you must choose the options where Ed-e cancels the missile launch for this to work (see options in picture below). I have also included optional voice files for the dialogue options that I have changed.
