If having a happy ending is in there somewhere somehow invalidates the unhappy one, I question the veracity of claims that they like dark, tragic, or bittersweet endings after all.
We are talking about people who like tough choices. Such people like weighing the pros and cons of each choice in order to determine the optimum path forward. In this capacity, they are STILL interested in the "best" ending, which can often be the happiest one. For someone who takes their choices seriously, a happy ending alongside unhappy ones invalidates the process of decision-making and makes it obsolete.
People who like dark-toned endings are a different discussion. In this case, it depends why they like those sorts of endings. Usually people like these endings for a reason: one that comes to mind is that usually dark or tragic endings result as some consequence of an unfortunate series of events, as a consequence of a character making the wrong decisions because of a flawed personality, because of some set of circumstances that are beyond the main character's control. People can like that a story takes those sort of challenges seriously and does not handwave them purely in order to produce a happy tone.
Personally I do not believe that the current endings feel like a natural progression of unfortunate consequences (or fortunate ones). The endings are contrived both to be sad and happy. For example, why does Synthesis need Shepard to die? That's a contrivance to alter the tone. Similarly, having your squadmates escape the beam rush without explanation (in the OEs) is a contrivance to alter the tone in the opposite direction.
However, pointing out the flawed ways that the ME3 endings manipulate the tone is not an argument to install a happy ending alongside other flawed, non-happy endings.
