Now that I have read through ALL of it (not in detail for most part), I'm here to bring chaos too.
The title caught my interest because it's almost like 4 people who are going to be together (the title shows four names). So... why not (writing this in a nuclear bomb shelter with all the keys for the lock on the entrances are melted down, while wearing a Hazmat suit)...
[spoiler]...let both happen? Ai will make an antidote that can only turn him back temporarily (for a week or something). This will allow for a LOT of pairings if they don't mind having a double life (or take it to the extreme with Tiger woods

)
In these cases, ShinxRan, AixCon, GinxSherry are possible. You can think of more for this funny joke of mine.[/spoiler]
If you guys have that many polls, you can do a meta-analysis

AND someone should just post all sides of the argument for all the pairing in ONE easy-to-see post (without the ad hominem) in a EASY-TO-FIND place (not page 34, 75, 156, 217, etc. of Ai x Conan thread). I have given up on reading the threads with pairings because they usually are TOO long (I've only been able to follow Conan x Ayumi and the unusual ones because they're more manageable).
Conia, does your cupid powers work in these cases?
