I think there is a lineage of science fiction name coining that whose progenitor is Edgar Rice Burroughs' Mars stories but that passes through early to mid-20th Century pulpier sci-fi like the works of Edmond Hamilton and Jack Vance to the galaxy far, far away of the Star Wars Universe.
In his Mars stories Burroughs went for relatively short (mostly 1-2 syllable), two part, phonetically simple names. Though they don't mostly sound that way to modern ears, I suspect Burroughs was after what he thought of as an "Oriental" feel. They also wind up being very simple for English speaking readers to pronounce. Examples: Kantos Kan, Gan Had, Ras Thuvas, Sab Than, Sojat Yam.
Burroughs uses a not hugely different style in many of his Planetary Romances.
Edmond Hamilton was clearly influenced by Burroughs in a number of ways and the naming practices in several of his works are similar, though they are a bit more phoentically diverse and have more consonant blends. Here are some names from his Captain Future series: Sus Urgal, Re Elam, Thuro Thuun, Rok Olor, Si Twih, Brai Balt
Typically, he doesn't always try to be so "exotic." Sometimes he seems to be trying to convey future developments of English names. This tact he shares with other writers of the 1940s-1960s, including the various creators of the members of the Legion of Super-Heroes in DC Comics: Irma Ardeen, Rok Krinn, Garth Ranzz, Tinya Wazzo.
Jack Vance tends to take this latter approach in some of his science fiction, too, though his names are more often multisyllabic and have a first-name last name pattern with each name sometimes made up of more than one element. Still, they have a similar vibe I think to the Hamilton and Legion names. These are from the first two Demon Princes novels: Miro Hetzel, Conwit Clent, Lens Larque, Sion Trumble, Kokor Hekkus, Kirth Gersen.
Star Wars names aren't the product of one individual, though later writers have obviously tried to fit the standards of the original trilogy. There are more straight up English names in Star Wars and of course some pseudo-Japanese ones, but a number could easily have been characters in Captain Future stories, like these: Ric Ole, Sio Bibble, Pondo Baba, Plo Kloon, Nien Nunb, Mace Windu, Sy Snootles.
