If Maki died instead and Mai’s CT fully developed, would it be similar to Yorozu’s CT?

So I know because Mai died, she took the remaining cursed energy in Maki and shared between the 2, as twins are viewed as 1 in regards to cursed techniques. Mai doing this, fully developed Maki and finally brought her raw HR to the level of Toji’s.

Soo, if it went the other way, and Maki died for Mai, would Mai’s technique become fully developed? And if so could it potentially be similar to Yorozu’s technique? If so again, does that mean she could form a perfect sphere?
