I little idea for CB when they design some of their next few models. Design 2 different models to specifically allow arm swapping, but not necessarily the same type of troop. If you check out the profiles for the Barid & Farzan they both have Rifles & Boarding shotgun profiles (and are in the same sectoral). It shouldn't be too difficult to design them to be arm swappable between the 2 blisters. The only thing I can see is that one has a pitcher, but that could be a small glue-able piece under the weapon. Pros: Same number of SKUs Customers who only want 1 of each don't have to spend more Customers who want everything will buy the same product twice Cons Design cost slightly higher. May require extra bits (Pitcher in example)
