There is nothing worst to a server to be considered custom, and even if you try to justificate it with arguments it doesn't change the fact that if someone plays in naxx and finds mechanics that weren't on retail, then it will be considered as custom.
If you increase the hp and damage of the bosses, it won't be so notorious. So my vote is for either leave it as in retail or increase the hp and damage of the bosses.
