Well, we know that 10 years later, N/newL would most likely be alive. At least he was alive 1 year after the event, when we see him talking about one of the people who had the Death Note but said he wouldn't take up the case because it wasn't worth it, and eventually the guy ended up dying. The point is, when 'L', the currently 10 year old girl was born, N was still alive and had picked up the title L (since the first L's death was never officially announced, I believe). The possible successors from the orphanage were all given different letters so naming one L is just plain weird. I don't think that their names actually change at one point and having the name 'L' probably doesn't automatically make you the successor, as seen in N and M's cases. If it did, that would mean they would have decided she would become the successor the day she was brought to the orphanage or perhaps the day she was born, since she apparently already has a reputation for being a great detective and was probably in the orphanage for quite some time. It's absurd to have 2 Ls at the same time and have one of them be the successor of the other while the letter doesn't really carry any meaning.

When did N write his name in the Death Note? Certainly not during the events of the manga. N still being alive for the fake Kira was part of the manga where he didn't write his name in the death note, so in that canon he would be alive still for that very reason. If there's a canon (from a book or something?) where he did write his name in the death note it's not part of the manga, so him still being alive (or death in 23 days if he did write his name in the death note) in that canon doesn't really matter for the events of the manga. For the revival plot, are you speaking of the Death Eraser? That was part of the original concept used in the manga's pilot. That idea was excluded in the official manga.

Not saying for sure that we can't use stuff from non-canon parts of the death note series (or if other things are canon then that's fine too), but I'm just basing things off of the manga for this roleplay at the moment.

As for the naming scheme of the orphanage, I'm under the impression that our characters didn't have any part in it, although some may or may not have as a personal preference. The orphanage was to see who would become L, while all we are is detectives working together. Thus we don't need to care about the naming scheme of the orphanage.
