"Can an Index be Split? Exploring the Possibilities and Consequences"

Can an index like the Bank Nifty be split in the same way as individual stocks, and what would be the potential consequences if such a split were to occur? Additionally, is there any other way to modify the composition of an index like the Bank Nifty that could affect its performance?

I don’t know anything about BN but I think if BN becomes too big to handle technically, maybe they can be a split. On the other hand, Nifty is the most traded, so they can handle BN too even if it gets too big.
