Initially, before I read the content of the page, I've been thinking to put this as a proposal. However, not just that there are no reasonable linguistic basis, but I see the proposal [1] as edgy in the sense of trolling.
My comment with rejection is:
According to the article Reforms of Portuguese orthography [2], Portuguese and Brazilian philologists and institutions support unified language. Consequently, the basis for the request doesn't exist.
