Is it permissible to change the letters of Quranic words, such as "خلقناك" (khalaqnāk - We created you) in the narration of Khalaf from Hamzah and "خلقتك" (khalaqtuk - I created you) in the narration of Hafs from Asim, knowing that both narrations are authentic?

Some reciters read "خَلَقْتُكَ" (I created you) with a ta' (ت), while others read "خَلَقْنَاكَ" (We created you) with a nun (ن) and an alif (ا). Both readings refer to Allah Almighty. As for the reading "خَلَقْنَاكَ" with a nun and an alif, it is for the style of magnification, indicating the greatness of Allah. This is because the plural form is used in Arabic speech for a single great being who has helpers, just as kings do. There is no dispute in the Uthmani Mushaf's writing between the two readings, as the writing is the same despite the difference in the manner of recitation. Both readings do not contradict the Mushaf's script, because the alif is dropped in such constructions.
