Thats definitely a very solid core EonX-, i really like the idea of mixed Emboar too!, it seems like a really nice mixed wallbreaker that could clear the way for quite a few Pokemon, whether its another Fire-type such as Entei or as you mentioned, Choice Scarf Braviary. I don't have much experience with Choice Specs Mesprit just yet(although it seems pretty cool to me :o), but i can say from experience that Choice Scarf Braviary is a pretty good Pokemon in the metagame: Flying is a pretty good offensive type in the current RU, especially with the coverage options braviary has to get rid of the Pokemon that could take Flying-type moves between STAB Return and Superpower. Because of this and Braviary's raw power (really high compared to other scarfers tbh, especially because it runs a +attack nature) Braviary makes an exceptionally good revenge killer, and its really good at cleaning up afterwards to boot. As mentioned, Stealth Rock is problematic for braviary, but the american eagle is lucky enough to pair well with the best spinner in the entire tier: Kabutops, making it less of a problem if you can get the opportunity to get rid of the hazards. As for possible threats to the core: i could see Choice Scarfed Electric-types being a problem, especially if the core is paired with Kabutops. Braviary is easily forced out by things like Rotom-C and Manectric, and although Mesprit and Emboar aren't weak to Volt Switch, they still dislike taking them repeatedly, especially because of their lack of recovery, and the opponent can easily switch into something with a good matchup against the switchin. Therefore, when using this core i'd probably pair it with something that could take on these Pokemon well, such as Druddigon, Golurk, Rhydon, Lanturn, or even things like Roselia and Amoonguss. Another idea would be to try out Healing Wish somehwhere on Mesprit, Of course this means that she loses either a coverage option or U-turn, but Healing Wish is a really useful move, and it makes Braviary that much more dangerous when Mesprit can fully heal it at any time, specifically when nothing else could stop it from sweeping.
