By raw, No.
As Joel stated, the target of the spell is not a specific body part.
It is rare that the listed target of a spell is say, "an arm" or "an eye" or , "a head" but often spells still affect those specific parts, and it makes sense to me that the magic would be concentrated there. Permanency does last into death as well, and will return when revived. It may be possible to either transfer the enchantment, (Gm Fiat, probably some sort of spell research.) Or if the gm is willing, your suggestion is probably something I would allow, in part due to the wording of the spell arcane sight stating it makes you eyes glow, to me implying it concentrates the magic there. Requiring high heal or survival checks to remove the eyes, and keep the magic in tact. Defiling your friends corpse, also not an act of good. Alignment hit should be expected. Both of these methods are GM discretion. Table results may vary
