Nephis is still titan [Chapter 2971]

A lot of people are saying how it doesnt make sense how nephis is still titan after exploding her 6 cores and I might have a theory

When sunny first obtain 2nd core he was changed like even without his essence his body was strengthened, what if same thing happen to nephis that their bodies are permanently changed by expanding to seven cores so even though she lost sex cores, her body was before changed by adding all those cores, so she still has strength of titan even though much much lower than before because of missing cores? what do you think
