The trouble is, although it's understandable to want to make such a small change for the fun of it, the time of such tweak mods has really passed. Of course you are free to play around with them on your local computer but it is unlikely to make it to publishing on the public system.
Over the last few years, the mods system has gone through many stages, ups and downs and now mods are not published unless they get community support. There are so many good mods now, the community won't really support mods that don't bring something new and interesting.
