Looking at Dehaka's Adaptation (Heroes of the Storm), could that be applied to a League Champion?

Here's how it works:

After 5 seconds, heal for 60% of the damage you took over this period.

Now, those numbers are probably wrong for League, but the idea of the effect is pretty strong, yes? 's Thick Skin might be similar, but it's not as skill-oriented and more of a "he'll get a second lifebar if you don't make him screw up his shield timing". And while 's Chronobreak has this kind of effect, he's not a tank.

Good tank skill? Or would it have to be adapted somehow?
