All that said, I always had a weak spot for this issue where he drew an old-school tussle with the Prince of Puzzlers, including a visit from Dick Grayson on break from Hudson U:
Chan's art worked for me on this story, with it's "updated Infantino" vibe, where it did NOT work so well in "spooky mystery" mode.
I remember that "Super-Gorilla" issue fondly. The Batman story, from the 40s, was a nicely creepy one with a crime boss beating the electric chair by having his brain surgically transferred to an ape, only to end with the gorilla falling off a building and onto his head.
A few months after this reprint, a "sequel" of sorts appeared in a (then new) story for World's Finest, where the brain is transplanted AGAIN into the body of sort of flying stingray from outer space with powers to threaten even Superman.
