Not sure about that. It is always dangerous to tamper in the generated files, because they will get easily overwritten on a new build.
The I2CHW component does not offer a different port there might be some internal tricks involved. to be really sure, I would suggest you to get in contact with Cypress directly: At top of this page select "Design support -> Create a Support Case" and ask your question. You will be helped by a Cypress engineer.
