Here's a couple of straightforward (but a little fiddly) customs:
An Ithorian merchant (I haven't built a back story for him yet). I like this because it shows the basics for building a custom Mok Shaiz out of existing parts (though you might have to design a vocalizer) in case we never get one (oh...Scoundrel's Stock has a cast that works perfectly for the head also):
Recipe:
Head, hand and legs = POTJ Momaw Nadon (courtesy of JDeck)
Body = Meena Tils
And...SA Mudtroopers:
Recipe:
Heads = Han and Mudtrooper from the Target exclusive Solo Movie figure pack
Body = the "incorrect" Target exclusive Migs Mayfeld (Morak)
I guess this is a "Target Exclusive Custom"
I had to clip the breathing tubes from the backpack of the 5POA figures and glue them on. I'm still debating the cloaks. I may use little magnets to attach the plastic ones from the 5POA figures, but I'm also thinking about trying to replicate the cloak with actual material. We'll see.
