All weekly expiry's same day vs what sebi did

Instead of what sebi did rather than curtailing BN,AUTO,FIN,IT nifty weekly expiry what would have happened if all expiries took place on the same day every week. Rather than a each on each specific day of the week. From a hypothetical scenario pov how would this impact momentum?

pushing for all weekly expiry’s on the same day would have been a better initiative than banning.
