While, yes, having Kyon as the guy would make for some intresting inner multilogue... your problem ther is simple: Game Mechanics.
Specifically, if they aren't powerless voices of annoyance in Kyon's head... Belldandy will contact a higher spiritual power ASAP... now think carefully about what that means in that series. Think of the series' cosmology. First, all it does is given Kyon and the leader of the S.O.S. Brigade a mindlink... with 5 extra people involved... which is likely to unmake that reality rather soon. Next, she contacts the the overbeing... which is OverHaruhi or OverKyon depending on how your dealing with things... which means that 1) spamfic reset (which isn't the goal) or 2) Epicfic dealing with the nature of that reality which is just not the point of blackaeronaut's fic idea. In fact its the inverse of that idea. So instead Belldandy manages to contact the ITE... which means the voices get there own bodies or suppressed... with again isn't the point of the stated fic.
Anyway I look at it that series, it has too much baggage/mythology to work in this context.
