Honestly, the bandicoot was my oddball choice. I know the other animals, except maybe the horned lizard, are mentioned a lot. Also, kind of wanted to spread it around to multiple areas, and figured I'd throw in a fun critter from Australia to round it out. I'd be fine with your suggestions too. Especially the Quoll, cause the Eastern Quoll is found in shrublands and is another fun critter from down under.Bat-eared Fox >> Bandicoot
OR Serval which would be well received by the community, Honey badger, quoll there are so many...
I like your other choices though! UNLESS you want the bandicoot as one of your top wishlist animals? Then, yes, its a perfect roster.
I just think bandicoot's kind of random... That's all.
