So. I went ahead and did this. I got a shurnk down version of Kenner's cardboard Sears exclusive cantina backdrop. Then I sourced 3 lead gaming minis that would work for Tatooine and scale to Kenner's Micro Collection. I gave these figures a "toylike" paintjob and display them alongside 3 mint loose Kenner originals.
Rogue One and Jabba's Palace are next. Along with something too secret to divulge right now.
