It is amazing how the same image strikes people differently. A body-swap storyline never entered my head.I've run across several comic book covers that seemed to me to be just begging to be done as bodyswap storylines. I think that I've had them filed away too long trying to think of other storylines that might go against the most obvious readings, so I'm going to post some of them here.
The first one,
Fight Against Crime (Story Comics, 1951) #16, 1953, looks like it might actually be a bodyswap story:

For the 2nd,
Gene Autry and the Wildcat - Four Color #0075 (Dell, 1942), it was the turnabout in the roles, plus the over-rouged Gene Autry, that suggests a bodyswap for me:
Romantic Story #128 (Charlton, 1954) could easily be a Medallion of Zulo story in my opinion:

Andi has been using the various Confessions of the Lovelorn for the Confessions of the Transvestite series, but this one might have to be a Confessions of the Bodyswapped:
Confessions Of The Lovelorn #58 (American Comics Group, 1954)
