How can I change the character of my secret base?

[Scarlett]

Hello, I am trying to change my representative trainer in my secret base in Pokemon Emerald

I change the gender and ID of my character with PKHeX, but the trainer of the secret base did not change, could you help me?

 

I think it is necessary to modify a value of those that are shared in the mixes records, but I do not know how to do it

Did you try deleting your base and setting up a new one before mixing records?
