I'd like to join in if I can, I have a USS Valley Forge 1950 Project in mind, building an Academy F9F, Tamiya AD5 and an AMP HO3S-1 Possibly an Hasegawa F4U-5N

That would be a great idea, I kind of do this already.
To maybe make it a bit more attractive, perhaps you could add in that one of the subjects of the double could be an already built kit?
So how is that any different to modelling an aircraft depicting a particular pilot, with the weathering etc to show the stress of battle? or a tank in a similar vein, or even more so a a diorama?
"Slapping a coat of paint on a wall" can indeed be art, it creates a mood or a feeling.
