Some other ideas given the initial author notes:
Voki needs to seriously consider all the potential cost/benefits if he takes those suppressor jewelry off. On the bad side he might be more vulnerable to heat, look blue, and potentially vulnerable to anything that affects frost giants or giants in general. On the potential good side he might actually be immortal or extremely long lived even without any Idunn apples. The frost giants do not appear to have any immortality food or drug and appear to have comparable longevity to the Aesir who are using them so he might enjoy similar life span (or perhaps magical frost giants might even be immortal compared to "non-magic" frost giants due to the magic).
Presumably he will discard any real interest in ruling or having much to do with any frost giants given that he will likely be treated as some freak by them due to his size and probably what little he can know about them puts them as being all too similar in personalities with the typical Aesir (with the exception of "giant maids" and "giant crones" who have many powerful magics but they are generally portrayed as ones who probably would stab him in the back at first opportunity and even if they knew of his giant ancestry they probably would look at him as a deformed giant).
Another consideration is why is he interested in being known as a god of magic? Would he gain any real advantage to do so beyond bragging rights? Does he get power from worshippers or being called upon by invocations by sorcerers (like Doctor Strange) (implied in the comics but not really explored)? If so, he might want to see if he can change his name to free himself of anything to do with the Aesir. If so, maybe if Doctor Strange loses the infinity stone, Voki could give him (as a potential gift for alliance or to encourage invocations) something like the comic version of the Orb of the Agamotto and the Eye of the Agamotto (assuming that the Vishanti group of beings are not around to give him those things).
