[Comartemis]

So judging from the information we have so far, here's what I've come up with for the recreation of RF6:

First, note that this timeline goes with the assumption that Hayate joined the navy as an Enforcer and became captain of her own ship for a while like Chrono probably did prior to attaining the rank of Admiral. Hayate has a few connections in the admiralty and among the Main Branch which she uses to keep the force together for the most part, so this is rather important.

The limiters and the balance of power is a concept which is almost entirely limited to the ground forces thanks to Regius's reforms. Because the ground forces are almost entirely made up of D through B-ranks, limiters don't usually come into play unless a bunch of heavy hitters from the Main Branch or the Enforcers set up shop in Ground Forces territory, and since RF6 is backed by the Saint Church and Admiral Chrono, neither of whom has anything to do with the Ground Forces, those limits are in full effect for the duration of RF6's stay on Mid-Childa.

However, once RF6 has served its' purpose in the eyes of the Ground Forces, it is forced to disband. Here, Hayate exerts a bit of her influence and asks a personal favor of a former colleague of hers, Admiral Cyphus Kain, Hayate's mentor who taught her everything she knows about leadership and a commander's place on the battlefield (right up there on the front lines next to his troops). Cyphus gladly welcomes her and the personnel of RF6 into his fleet, and after a bit of effort shuffling things around and getting some papers signed here and there, Hayate winds up being reinstated as the captain of her old ship. RF6 now makes up the crew of the TSA battle carrier Beginner's Luck. There are a few stipulations to this, as the crew has a few new higher-ups they have to deal with in addition to Hayate and Cyphus, but all in all the team sticks together with the possible exception of the Forwards, who might decide to go on with their lives the way they did in the StrikerS epilogue.

As we've already established/theorized, the navy places less stringent requirements on the balance of power in its' fleets, so Hayate has little trouble getting the crew to stick together, though Fate, as an Enforcer, will have to float around the fleet and do time serving on some of the other ships every now and then. Nanoha, Signum and Vita serve as commanders for the ship's sizable garrison of combat mages, while Shamal is the leading medical officer and Rein II is the ship's first mate.

It's rough and undeveloped so far, but can I get some opinions before I get too caught up in this line of thought?

*EDIT*
Actually, scratch that line of thought. I just realized the Special Investigations Officers are probably already part of the navy since Leti's the one who decided to let Hayate and the Wolks stay together. All we need in this case is Hayate's association with Cyphus during the manga timeskip, and since we assume that SIOs spend a lot of time on warships like Chrono and Fate do, she can probably be reasonably be given a spot as the captain of a small cruiser after StrikerS, considering her experience as RF6's commanding officer. Nothing big, just something for a newly-minted captain to cut her teeth on before moving up to a frigate or a battleship once she gets some experience under her belt.
