I don't know, it would certainly make some things more convenient, but it would be at the expense of diversity, some beautiful languages out there, and language generally fitting the culture it belongs to. Also English is a nice sounding language, but it's notoriously difficult to learn as a second language because of so many homonyms, because of so much inconsistency in pronunciation vs spelling, because of how many words there are including many synonyms, and maybe because of the plethora of idioms in everyday use.
