I had been considering it at one point, but I was questioning the idea before finishing the original since the consensus was that it wasn't as good, and that assessment has me even more wary now. Based on what I know of 0 (I waited until I was finished before reading up on its scenario and have some idea where it's supposed to lead) and what bothered me about that ending in the original, it doesn't seem like it would help.If you didn't like the true ending, you should try Steins;Gate 0. I know it's weird, but it's a good game for people that didn't enjoy that particular ending.
EDIT: It might help if I elaborate...
My issue wasn't with the fact that Okabe actually succeeded in saving Kurisu and averting WWIII, although one could argue that it seems improbable that he managed to somehow fight against convergence with a change in plan in spite of attempting to stay one step ahead never working whenever he tried to save Mayuri (when fate wanted her dead, it didn't matter what he did, it was going to happen). I wanted both Kurisu and Mayuri to live in the end. No, other things bothered me personally.
Honestly, I didn't care for the decision to actually have there be an official couple in the story, and this is coming from someone who quite liked Kurisu. Given the atypical approach to multiple endings in a VN, where instead of having multiple bad endings there were multiple bittersweet, romantic endings, the idea of there being one "right" answer tied in with the true ending invalidated every other possibility. Not leaving things ambiguous after all was said and done made it abundantly clear that the players' interpretations were of no consequence. I can also add that even with Kurisu's support throughout the course of the story, such a turn felt like even more of a swerve given all of the pain and suffering that Okabe had inflicted upon himself and everyone else for Mayuri's sake (in fact, she would've made far more sense to me if they absolutely had to insist upon a canonical pairing, regardless of the typical "she's like a little sister to me" protests coming from Okabe).
Then there's the epilogue on the Steins Gate worldline. Even after all of that, the promises of it being an ideal unobserved worldline, neither Luka nor Faris were allowed to have their wishes back. Luka would've had to come to terms with Okabe's heart belonging to someone else, but still could've been born as she wished she had been instead of being stuck with having to change back. Meanwhile, Faris' father was still dead and gone, yet another sacrifice made for Okabe's objective. I was willing to be somewhat forgiving toward Moeka following the events of Chapter 9, insofar as hoping that she would have a chance at a normal life and not be in any position where she felt compelled to hurt anyone to cling to the place she felt that she belonged, but honestly wouldn't have wanted her anywhere near the other lab mems again. Naturally, Okabe preparing a pin for her and inviting her back to the lab rubbed me the wrong way. Didn't think much of the idea of the lab still staying above the likes of Tennouji either, whom I didn't forgive at all. In fact, upon meeting with that trio outside of the Braun Tube Workshop, Nae was the only one I was willing to completely forgive after all that had happened.
Yet for everything that Luka and Faris had lost, Okabe ultimately had to sacrifice nothing. He had gotten everything he wanted, including reuniting with Kurisu after her memories of their time together had returned once they were triggered. Each and every one of those character-specific endings (with the exception of the one for Kurisu, since it was just a cut-off version of the true ending anyway) felt more meaningful because unlike the true ending, he had to lose something too in exchange for what he had gained.

This is why I don't see diving into 0 fixing any of that.
