There not necessarily being a problem with it doesn't make it necessarily a good mechanic. (Though, to be clear, there are problems.)

A good mechanic is enjoyable to play with and around. Losing max HP just means that your nukes timings are contextually restrained and draw resources from your ability pool and from your cohealer's (along with possibly their uptime).

More importantly, your Sacrifice mechanic creates a balancing nightmare, as you cannot both tune the kit for high-damage-intake environments like Savage and those in which both the loss to max HP is nonthreatening and the loss to HP made up for off your oGCDs alone.

You'll thereby have introduced a mechanic that will more likely annoy WHMs than be enjoyed by them, will definitely annoy your cohealer, and has virtually no payoff or affordances.
