While it's entirely possible that Ran and/or Shinichi could be killed (or unable to recover in age), it seems unlikely, and that's the only thing I can think of that would prevent an ending with them as a full on couple.
That said, I think it's very clear that Conan has feelings for Ai, and it's a stronger bond certainly than with many others, but I don't think it's something stronger than his feelings for Ran. Ai, from what I can see, seems like she's in love with Conan, but recognizes Shinichi and Ran's feelings for each other, so will do what she can to support him both in that, and obviously in general. A non-selfish type of love. Conan might love her... but I think it's more "like a brother" and the "really close friend" type, also willing to sacrifice for her. Such that if he had to choose between saving Ai or Ran, he'd either go after the one he thinks is in the most danger first, or try to save both at the same time. That's the sense I get from it.
I don't really support any particular pairings myself, but so long as they don't pull the character in a really random direction (unlikely due to how much character development has gone into him over the years)... I'm fine with it.
