Customizable Sprite Pitch Limit

[0mnicydle]

So basically I'm wondering if it would be possible to have Y-axis sprite billboarding kick in only at a specific view angle, after the sprite has already been pitched to a certain degree. In other words when looking straight down 90 degrees at a sprite, instead of a practically invisible sliver we instead get to see a sprite which has been pitched to say 80 degrees, and billboarded the rest of the way.

EDIT/ Actually when I look in the game options right now the axis labels used for the existing options make it seem like the what I think is Y is actually X for some reason, buy hopefully my meaning is clear.
