I actually do sing different words in hatikva, based on a recording I heard from pre-war europe in yad v’shem.
They sang:
??? ?? ???? ????????
????? ??????
???? ???? ???????
???? ???? ??? ?? ???
But, the only part of that I like better is that the tikva was “lashuv l’eretz avoseinu”, I don’t really have a preference whether it was a tikva noshana v. shnot alpaim. So I sing shnot alpaim and yerushalaim, but eretz avoseinu.
