Idea: A Code Geass Story where Lelouch stays in Britannia

Synopsis: Instead of his mother getting killed by a brat with a bad plan, Lelouch's mother is killed by anti-Britannian elements from Japan, the Second Pacific war follows but instead of the whole of Japan being conquered only Kyushu falls. Now in the Global 2017 or 2072 ATB after hearing about the serious mismanagement in Area 11 the 98th Emperor sends Lelouch to investigate and eventually replace the viceroy, right as rebellion is in the air.

Details

Fanfiction: Code Geass

Type: AU

Elements: Realistic Military and political actions, OCs, different paths for Canon Characters, Combined Arms warfare with Knightmares and Emperor Lelouch with Dead or removed Charles.

Notes: No Geass (Or reduced involvement of Geass both in story and lore), empothis on the Great war and LelouchXKallen.

Rational: A Cold Calaus inspired this but I wanted to place a more focus on the world and characters without Geass, it'll still be there but it won't be discovered fully until during the great war after what I'd call the "Siege of Japan Arc" make of that what you will. There will be the JLF and a kind of Black Rebellion but they'll appear very early on and be the catalyst for the meeting of Lelouch, Kallen and C2 (Or C.C in the sub) the difference between C2 in this story and Canon is that she's less knowledgeable about Geass and Code if at all and the gang won't know about it fully until later in the story after the above arc I've mentioned. V2 will appear but as a adult and head of the OSI or whatever if you want to be more creative, as for Kallen I believe since Japan wasn't fully conquered she isn't as resentful of Britannia though she is still hot-tempered and has a bad past with the Anti-Britannian movements when she was younger (Kinda like Blake from RWBY) and will be the main reason why she'll be in Kyushu when shit goes down. (Along with her mother)

Another thing I wanted to do for this idea is more original weapons and gear other then just Knightmares (Because COME ON I know that some of us like things like the M16 but some of us actually LIKE the original weapons the animators came up with!) as well as more…I guess "wide view of the battles" would be accurate because whilst A Cold Caluas did mention many military units like the 24th Infantry the battles and war as a whole felt…empty whilst I understand It'd take forever for the story to finish overwise the "great war arc" didn't feel like a great global war at all and as some who's knowledgeable in both WW2 and military tactics and structure in general I have evidence to back some of my claims up.

I had actually another story which was a crossover with MLP G4 where Twilight ended up in the Code Geass world and the storylines kinda blended in at points with the differences mostly being with or without Twilight.

AN: Here's my first idea let me know in the comments and if your interested let me know by PMing.
