Here's what I've found that was suitable (this is not an exhaustive search)

Dirha (grid s-9) was a gritty industrial planet [4] that was located within the Dirha system of the galaxy's Hutt Space region [1] and lay on the hyperlane [2] called the Sisar Run , [3] which connected it to the world of Cyborrea [2] and the Sespe system . [3] Dirha lay within the sphere of influence of the Vosadii kajidic , a clan of the Hutt species , [6] and served as a refueling point for starships that traveled along the hyperlane toward the planets of Nimban and Nar Kreeta . [4] After the military forces of the extra-galactic Yuuzhan Vong species invaded the Hutt Space, Dirha was terraformed by members of the species [4] between 25 ABY and 29 ABY [5] in a process called Vongforming.

Diyu (grid s-12) was a planet [4] that was located within the Diyu system of the galaxy's Hutt Space region [1] and lay on the hyperlane called the Shag Pabol , which connected it to the Rorak system and the world of Ylesia . [2] Diyu was a major industrial center that relied on slave labor for centuries . [5] The Anjiliac kajidic , a clan of the Hutt species , had influence on the planet. [3] When the military forces of the extra-galactic Yuuzhan Vong species invaded Hutt Space, Diyu escaped their advance. [4]

Rorak 4 (grid s-12) was an industrial planet that was located within the galaxy's Hutt Space region and lay on the hyperlanes called the Gamor Run and the Shag Pabol . Rorak 4 was orbited by the Rorak 5 space station and was the site of the largest slave market in the Hutt Space .
Rorak 4 was an industrial world [3] that was located within the Rorak system of the galaxy's Hutt Space region [1] and lay on the hyperlane called the Shag Pabol , which connected it to the planets of Nal Hutta and Diyu . Another hyperspace route called the Gamor Run linked Rorak 4 to the world of Circumtore . [2] Rorak 4 was orbited by the Rorak 5 space station and was the site of the largest slave market in the Hutt Space . [3]
The Rorak system was located within the territory controlled by the Hutt species at least as early as the year 11,000 BBY . [5] and the area of space surrounding the planet was considered well- explored by 8000 BBY . [6] The local population average of the region of space containing Rorak 4 around the year 25 ABY ranged from 10 million to 500 million. [4] At some point between 26 ABY and 27 ABY the Rorak system was attacked by the military forces of the extra-galactic Yuuzhan Vong species during their conquest of the galaxy, [7] and the star system was held under the control of those invaders until at least 27 ABY.

Hollastin (grid s-12) was a minor trade world located in Hutt Space , serving as a clearinghouse for goods from other outside regions. It grew greater in importance after the Yuuzhan Vong War as a result of remaining untouched by the invaders .
I'm thinking of using Diyu and making Grondo part of the Anjiliac clan
