I can't see Mattel doing it, but I would enjoy a pack like this.
I haven't gotten to it yet, but I've planned on displaying BA Randor with Marlena in her space suit in a sort of "Rescue from crash site" type scene. A younger Randor would be better.
I have the entire royal family together on a section of my display now, but have always been intrigued with the crash story of Marlena. I even wrote a fanfic about it some 20 years ago, which I just found again recently.
