Probably not, sadly. The only group that ever wants to change anymore is the mods and from what I remember the h-staff hated it because it was pain to arrange.
Not to mention that all the positions have most of the useable colors taken, so really, the only thing the mods could change to is another blue. That dark green would probably be too confusing.
Although at this point, I'd think it'd be awesome if the mods got a color change. I was never a fan of steel blue myself, although the teal was worse.
