Bat-eared foxes and aardvarks could be candidates to mix with animals of similar size, not only much bigger ones. Both have very reduced teeth, which could convince zoo curators they are not going to kill/eat their neighbors.
Fennec foxes could work, too with things like porcupines, warthogs, dromedaries, some domestic ungulates, mid-sized antelope etc. Most foxes of all species are very mobile animals, which have an innate drive to run for kilometers every day. They should be kept in much larger exhibits than their size alone suggests, and adapting an exhibit of larger animals to a mixed exhibit is an option.I saw fennecs put temporarily into an empty wild dog paddock in Dvur Kralove, and they were well visible and looked very happy.
