Mixed Keldeo doesn't sound good, especially when you can hit on the physical side with Secret Sword off your much stronger special attack stat to begin with. If you really want to setup, Calm Mind is still an option. I guess ingame it might work, but Keldeo won't hurt with physical attacks unless you setup and being forced to SD on every single battle is kind of annoying. Also, Stone Edge, Close Combat and Hydro Pump means you will have some seirous PP troubles unless you manage to PP max everything. And lastly, setting up only to have Stone Miss do what it's best at means you basically wasted two turns doing nothing.
Hone Claws over Swords Dance is nice ingame, though you could always use a Zoom Lens (or whatever Lens item boosts your accuracy) with SD to hit harder than Life Orb + Hone Claws after one turn of setup, get roughly the same accuracy, and eliminate the Life Orb recoil.
I don't see much in your team that benefits from having an opponent paralyzed (for Ferrothorn, it's counterproductive, Keledo's fast, Venomoth/Blaziken boost their speed), not to mention you already have Scald on your Slowbro. Try Toxic, or Slack Off, even Trick Room to play around with Ferrothorn. Psyshock is an option you should consider as well.
Leftovers over Life Orb on Honchkrow. Brave Bird gets you tons of recoil already, and once you get a Moxie boost you don't really need all that power to plow through everything. With Leftovers, Sub could be a nice option as well since it's very easy to predict when you're gonna get statused (first example coming to my mind is Cofagrigus at the elite 4)
Unless you really like stalling turns ingame with Protect, Bulldoze actually IS a good option on Ferrothorn. It's weak, but hits both Steel and Fire types (both of which resist your dual STAB) for super-effective damage, so as a coverage move, it is pretty solid. The whole "it powers down Gyro Ball" argument makes no sense, the AI doesn't switch so you'll never end up powering down your GB unless you misclick or something.
As for Venomoth, I suggest you use Psychic as combined with Bug Buzz, there's nothing that quad resists it meaning that will Tinted Lens you will always do at least neutral damage.
I like it overall (besides SD Keldeo D: ) hope suggestions helped
