Well, in the 20 seconds consideration I gave it, I didn't get the answer. However, when I read the solution I had the immediate "Ahhh!" reaction that I usually get from good riddles.
That said, if you're basing your riddle on obscure grammar, you have to use the grammar correctly. To do otherwise just isn't fair IMO.
The other, more important, consideration is in how you use this riddle, if at all. Here, it's important that the riddle not stop the adventure in its tracks. So, either have the room beyond the door be strictly optional, or allow plenty of other ways around. (Your idea of having the PCs proceed without the 'blessing' is a really good idea.)
Oh, and don't use the riddle at all if your players hate them.
(Also, if you have suitable props available, use those. This is an ideal opportunity to do so, and gives the players something to play with while trying to figure it out, which will help focus them on the task at hand.)
Also, it's a challenge, so award players XP for correctly solving the puzzle. A CR equal to the average party level is probably good. Don't worry about the 20% resources expenditure - they'll probably wind up using some Detect or Dispel Magics, and perhaps a Commune or Augury. And if they don't, well, clever them. No one said that a challenging encounter had to drain 20% resources, only that that would be the average.
