First off the fact soemthing is different then the Mesorah does not automatically diqualify it.
It does mean that you need really, really, really big people who know the entire Torah and have reached the status where they are generally accepted to be Gedolei Yisroel to change it.
Once I was at the Simchas Beis HaShoeiva of a major Rav( He is considered one of the major Poskim in the USA) and he spoke about this.
The point of his drosha actually was that Halachically it’s not prohibited but as frum Yidden we have a Mesorah and we follow the Mesorah and there was never such aconcept in Judaisim.
In the Chasam Sofer’s words,
‘Chadash Assur Min HaTorah”.
Sounds like (CV) “When there is a rabbinic will, there is a Halachic way”.
