I've done some thinking on this topic, as within Epic Encounters I had to design a status emulation system for many new statuses. As Abraxas* pointed out, as long as you're still actually using the base statuses you have some oddities that you won't really be able get around. It is absolutely possible to create new "fake" variants of these statuses, however it would take quite a bit of annoying work to create and have all old skills use these fake variants. To readdress the original post, though, it's not doable without significant work.
