I used it to make myself immortal with well over 400 trillion health, magicka, and stamina, then forged a sword that did over 500 billion damage points. I understand that that sort of thing isn't really canon (or physically possible for that matter), but if that kind of power could be bound to the physical form of a mortal, I'd be willing to say that some of their powers would rival those of the Et'Ada, and likely be able to match the power of any avatar that a Daedric Lord could assume. Though hadn't Mannimarco planned on using the Amulet of Kings to absorb the power of Molag Bal, with the Amulet supposedly being the most powerful soul gem in existence? But I doubt an artifact like Azura's Star would be powerful enough to trap a Daedric Prince's soul. Although the Dragonborn's (who has an Aedric soul)  body seems to act much like a powerful soul gem, able to (in theory) hold an unlimited number of the souls of dragons (which are in some aspects more similar to the Aedra and Daedra than other living beings), so perhaps there might be some sort of thing that could work out if they acquired enough power from various artifacts.

Mortals can potentially become incredibly powerful, yes. However, you cannot achieve powers rivalling those of the Gods without becoming a God yourself: Talos is one of the most powerful entities in creation, and was once a man (well, men): however, he is also a God, having mantled Lorkhan and achieved CHIM to secure his sense of self. Even then it can be argued that he was no ordinary mortal, as at least one part of him was Dragonborn, and at least two were Shezarrine.

With the exception of the Last Dragonborn, who is inherently divine, every Hero's "power" is dependent on his equipment and his skill: to rival the Gods, "power" would need to be internalized rather than wielded. The Last Dragonborn is a bit of an odd one out when considering the other Prisoner-Heroes, as he is no ordinary mortal, but effectively an Aedric Ada in the vein of Pelinal Whitestrake or Morihaus Breath-of-Kyne. Dragons are shards of Aka Time Dragon, the primary difference between the lesser Dov and major Aspects such as Auriel or Akatosh being the size of the shard that was mythopoeically shed from the Aka-Tusk.

As for the general topic, and whether Daedric Princes can be killed? No. They can be banished, but they always reconstitute themselves in their Plane of Oblivion. Even Vivec with the powers granted by CHIM, something that can alter the very nature of the Dream, could only banish Azura to Oblivion.
