There is a long history of Jewish communities creating Hebracized versions of various writing systems (Arabic, Latin, etc). Did such a thing ever happen with ancient Egyptian? Are there Hebracized versions of Egyptian Hieroglyphics floating around somewhere?
Possibly, the earliest know evidence for a 'alphabet' is the Proto-Sinaitic script from the Middle and Late Bronze Ages; some evidence suggests that elements of it were derived from Egyptian hieroglyphs. I have attached some sources to help you read further:
