That would be a "yes." This would be my version of Rowling's epilogue; after "Trinity," any sequels, and so on. It's an actual end - although, oddly enough, I still have ideas about where to take it from there (either another world-hop, this time on behalf of the Powers That Be, or they actually do break into Hell to rescue someone).
EDIT: And regarding the last Bayonetta snip - before I came up with the whip, I was actually considering having Galen's weapon being Osiris.
I realise that Bayonetta's canon has Eva as an Umbran Witch contracted to Sparda (which makes sense), but I could see the Angelic version of Eva representing Caritas, or Compassion/Charity/Love - which I think is Galen's cardinal virtue . . . Of course, that may be arrogance/ego on my part, too.
