Getting the plague, getting there alive as a Zombie, then walking to Baron while keeping yourself alive (losing health over time blows) is a long tedious adventure, which would easily take an hour at least. In the meantime, you could have already killed him several times.
If you really want the mount that bad, just find a friend to go with you and duo the whole place in 8-10 minutes. I mean, if you can convince someone to wait around for your zombied self to walk to the Baron, can't be too hard. I've duo'd it at 65 with pally/druid in 15 minutes with less than worthy gear. So, interesting exploit, but no where near fast when you take into account everything you need to do to actually exploit the instance.
