Sean Leary,
I assume you are asking about other American holes called "Redan" early in Merion East's history or before.
The seminal article on the the Redan concept in America was (and is) CB Macdonald's and HJ Whigham's 1914 Golf Illustrated Article called "Redan at National Golf Links" from their brief but excellent series on "Representative American Golf Holes." This "Redan" article discussed the original Redan hole at NB and NGLA's Redan hole, and also briefly described other American examples of the hole:
There are several Redans to be found nowadays on American courses. There is a simplified Redan at Piping Rock, a reversed Redan at Merion Cricket Club (the green being approached from the left hand end of the tableland) and another reversed Redan at Sleepy Hollow where the tee instead of being about level with the green is much higher.
CBM played a large part in in the design of each of these courses, but as near as I can tell neither Sleepy Hollow's Redan nor Merion's Redan were a close match the original. Both of these holes were reversed (and thus didn't perform as Redans for right handed golfers) and as CBM/HJW mentioned Sleepy Hollow's Redan was more of a drop shot, which (arguably) also defeats one of the primary design elements of the hole (although like with Merion, the design elements are pretty much out the window with the reverse nature of the hole.) The article also speculated that Pine Valley would feature "the Redan principle," but that this hole (the 3rd) would also feature a tee set well above the green surface, so ti wasn't a good match either.
Also, as explained by Mark above, many of the later CBM/Raynor Redans wouldn't stick closely to the original either.
So when you ask whether there were other holes that "didn't fit the bill" I guess it depends on what you mean by "the bill."
- CBM and HJW called these holes "Redans," and emphasized that the concept was quite broad, so they all fit the bill: "The principle can be used with an infinite number of variations on any course." so all of the mentioned holes would qualify.
- But for these modern day commentators who think they know better than CB Macdonald and HJ Whigham knew, "the bill" is quite narrow. None of the holes would qualify, but especially not Sleepy Hollow's, Pine Valley's, or Merion's Redan. In fact, as ridiculous as it may seem, both Rich Goodale and Sean Arble have long argued that not even NGLA's Redan hole is a Redan hole!
In other words, when these guys pronounce that Merion's Redan wasn't a Redan either, Merion's Redan hole is in good company.
Other than the holes mentioned above, I cannot think of any other examples except for the short 10th hole at Myopia which was named "Redan." Except for the name, the Myopia hole reportedly had nothing to do with Redan in North Berwick, and was reportedly designed based on a different hole entirely (the 2nd at Prestwick.) This was not the case with Merion, where multiple reports not only called Merion's hole a "Redan" they specifically discussed that the hole was based on the famous Redan at North Berwick and contained characteristics thereof.

Adam, as explained earlier in the thread, the front left bunkering may not have existed originally. Also, the grass in front of the green was cut short and running the ball onto the green was common enough that Flynn wanted to grow rough right up to the edge of the green. Apparently Flynn was not keen on the ground game option for this hole.
______________________
This last point merits emphasis. Conditions were different then than now, and under conditions of the time, the hole played more like what we think of as a Redan.
- The ground game was an option before William Flynn grew the rough right up to the edge of the green, and before the left bunker was added.
- Golfer's who tried to hold the green by attacking it directly faced a daunting task. According to Robert Lesley's 1914 description of Merion's "Redan Hole" the approach "requires the most delicate placing to hold the green."
