Can the avatar size be increased?

When Post_bit Legacy is used, it allows a bit more room then the standard post_bit (look at the dead space to the right of the current avatars). As the post_bit is narrow, the smaller size fits better...but using legacy means there is that dead space.

And in a quality post, there is even plenty of room for it be increased slightly for the height of it as well...but thats a bit harder to justify
