I like the way you consider the Devil ending to be not as gloomy as most others think. For either a good or bad character it's probably the best ending, because it's pretty much a guarantee of immortality from the people who designed the technology, especially if they sort out the cloning problem (but even if they don't), and since Hanako offers her services to the surviving V in some of the aftermath calls, it's obvious that your services as a resurrected evil merc would be desired, while if you're a good guy who still wants to take down Arasaka or whatever, well you have all the time in the world to dissimulate and plan it out
There's a hint of a Black Mirror type of horror scenario with the digitized rich and/or with you if you sign up - e.g. working as a digital slave or whatever - but I think that's a red herring. For the digitized rich, I think Saburo wants to have an immortal "court" that's loyal to him, and immortality for the richest and most successful would pretty much guarantee their loyalty once resurrected, while for such as yourself, it's the same type of idea. You've proven yourself and even to some extent shown loyalty to Arasaka, so it's far more likely that your resurrection as an effective merc (getting even better via the experience of an immortal) would be useful to Arasaka.
