Instead of the Master of the Forge...
Have you thought about adding korsorro kahn to your list?
This will 1) open up tactical options: You can decide to switch between Pedro's Chapter Tactics, for Kahn's Chapter Tactics. You decide after missions have been picked but before anyone has deployed. This can switch your army from stubborn and claiming with Sternguard to everyone outflanking.
Second, you can drop one Sternguard, one honor guard, and the MotF (215 points) for Korsorro (160). The extra can be spent in a variety of ways. What this gives you, however, more flexibility: Khan + Pedro in the Land Raider, Pedro + Khan with Honor Guard, or one 'n one in each vehicle.
Don't underestimate having Khan with Sternguard-- They can be charged, but with khan's hit n' run, they can get out n' shoot again--- even if they lose combat, because they'll be Ld 10 Stubborn-- they will pass, then just hop outta combat.
Just some ideas.
