Random nitpick here:
“The Aki-Aki species first appeared in the film Star Wars: Episode IX The Rise of Skywalker. In the English subtitles to the film, name of the species is misspelled as ‘Acky Acky’.” -Wookiepedia
You don’t have to change the spelling if you prefer it that way, but I also think the canon spelling looks better. Looks a little less like a child came up with the name lol. Not your fault of course haha.
I personally prefer it the way the subtitles and screenplay spell it for that exact reason. The first time we see the name is when C-3PO delightedly explains to them why the supposedly forbidden desert has a giant festival in it, and I feel like the more phonetic spelling punctuates the ridiculousness better for the joke. There are never any serious or dramatic moments directly relating to the Aki-Aki, so I don’t personally think it creates any jarring moments later to keep the more comical spelling.
