Exiles Nocturne is a sure thing. Angela Nocturne would also be a yes. Only got around to reading Marvel: The Lost Generation in the past year or two and surprisingly, I really liked it, since I wasn't thrilled about the idea. Would totally be in for The First line characters and their villain vampire Nocturne.
Biggest want here though is unexpectedly Nocturne/Graham Poldark. Read this miniseries while off during the pandemic and really enjoyed it. I think it's one of the first things Dan Abnett wrote and you can tell he's talented. Poldark is a fun character who really does come across as British. He's got his own villains and a connection to another English hero, Night Raven. I would definitely like to see more of him and would be enthusiastic to get him as a figure.
