From what I've been told, that's already been taken care of and the sculpt was made some time ago. I certainly hope that's the case since the Brig is at the top of my list for companions.
Doesn't matter when/if the sculpt was done: unless Nick Courtney was sent a prototype figure and said yes, they can't proceed with it. At least, not until his heirs give their yes.
Understandably, no-one wants to pressure a sick man, or a grieving family, so there can be a delay when the worst events intervene.
Well aware that a sculpt means squat without a release on the likeness. Which is why I said "that's already been taken care of" before I even mentioned the sculpt.
