This is the kind of thing that would be neat in theory, but I don't think it would be in practice. It's the sort of thing where people would start looking at their teammate's targeting square, and begin shouting "left! More to the left! Up! You got him!", assuming someone didn't just run in to spectate on a different character to address the line of sight issue entirely.

I'd rather we not incorporate too many LoS mechanics, personally.
