This is totally random, but I was recently re-reading Robert A. Heinlein's 1941 story "--And He Built a Crooked House--", about an innovative architect who accidentally invents a 4-dimensional tesseract house that he, his friend, and his friend's wife get trapped in, and I was trying to mentally "cast" the roles, and I thought of Dominic Cooper in Howard Stark mode to play the architect. And then it occurred to me that I could totally see the story rewritten into an MCU short film (or maybe a half-hour TV episode) with Howard Stark in the role of the architect, Peggy Carter in the role of the friend, and Jarvis in place of the wife. A few tweaks here and there would be needed to fit the characters, of course -- sort of like how Larry Niven adapted "The Soft Weapon" into an animated Star Trek episode -- but I think it could work. Howard isn't an architect, but if he decided to dabble in the field, accidentally inventing a 4D house is just the sort of thing he might do.
