I don't think it's a horrible idea, but like others have pointed out I think you need some way to balance the minis by their honor costs. Maybe you could even say that they have to get points equal to whatever honor they are. That way if I play Ojo'mon or Wilton I only have to get 1 kill. If I play Haruka I have to get 2 kills. It would also bring VPs back to it that would allow for some position and things on the board outside of just where you can attack from.
