I like MitsuAi for Ai. I think Mitsuhiko would actually understand if she told him, out of his brilliant imagination if not anything else. He's smart, he's cute, funny, and he's kind of like Conan. Shinichi, I believe, if he were to like Ai, he would have to force himself out of love with Ran, which I think is damn near impossible. Ran and Shinichi are just so darn stubborn! How long did it take for Ran to admit her feelings, how long did it take Shinichi, and how long is it taking for him to reveal the truth even though it's so darn obvious he wants to?! (proof of Ran's stubbornness: Oh look! What a happy coincidence! It's mom! Kogoro: You set this up again, didn't you? Eri: Ran, you've been doing this for the past five years, give it a rest already... Conan: *sigh*) Shinichi... Well... That boy simply never gives up. Even if it's untold in the manga, Shinichi and Ran do have a rich history together, and they've surely survived the ups and downs well enough to know that they want the other. And even now, after a year, you'd think one of them would just give up on the other, but neither have! Both are just as attached as the day Shinichi was shrunk, and if anything, separation has made them fonder. ('Separation makes the heart fonder' I believe it's a saying.) As for Conan and Ai... No matter how good a person Conan is, you can't expect him to easily forgive Ai for her mistakes, even if she had no choice. She basically ruined his life with that poison- he'll never get that lost time back. The time where he could have enjoyed high school with all of his friends, where he could have been a normal teenager, and maybe he could have been happy with Ran. Who could forgive a sin that great? I for one believe Ai needs a fresh start, one where she can let everything go and just become Haibara Ai. Miyano Shiho doesn't exist anymore- to the Organization, she's Sherry, to Conan and her friends, she's Haibara Ai. Just about the only person who knew her as Miyano Shiho, her sister, Akemi, well, she's dead. And Shiho died with her if you know what I mean. That's the main reason I don't believe in ShinShi (other than the fact I think they look quite strange together.). As for ConAi... Well... I'm just too big a ShinRan (and I'm quite a stubborn person, believe me when I say that) to support it even slightly. It can only end with one, and well, I'm just going for ShinRan.
