I've requested a replacement via kickstarter message to the folks who made them, but yeah if that doesn't pan out I'll probably consider alternatives.
Style-wise I'm not sure.
The dog, for example, looks a lot less blocky than the standard 40k cybermutt. That said, given a couple of well placed skulls, I'm sure it would fit in in no time. Right now the dog looks clean, but skeletal.
Similarly, the lady is in good scale, and has some sort of spinal thing going on on the back of her bodysuit. A few artfully places aquilae and/or skulls will fix anything that doesn't seem quite right, as otherwise she doesn't look too bad, albeit non-heroic.
She's got a sort of Imperial Guard/Imperial Navy grunt on the ground sort of feel to her.
Given that I've recently read Kingsblade by Alex Clark I am very tempted to have either her, or Borak's Noble as a Knight pilot, with her looking like she just stepped out of one, while the Noble looking like he's one dressed up to meet a bunch of other battlefield leaders or other diplomatic types for a discussion on strategies, or somesuch.
My mechanicus-style conversion of the Thorian might make a suitable sacristan-type character, albeit one who has equipped himself with a lot of weapons for the time being to protect his Knight from hostile intentions, maybe.
