I’m interested in seeing how it would look without English; I’m just saying - I think we need to consider what’s best for a first-time viewer, rather than what we might “personally,” aesthetically, prefer. The most important thing is that the message comes through to the audience, and I can’t imagine many folks out there know how to read Aurebesh.
And Jar Jar, English was in the very first Star Wars movie, as I pointed out in my clip above. So it’s definitely a canon language. (And again, I think clarity is the most important aspect here; there’s no point of adding all of this if it’s unintelligible to the audience. That would look like a fan edit.)
