A raccoon would work but it might feel a little out of place, I think I already suggested it but how about a Brazilian Porcupine or Kinkajous, for the smaller exhibit you could include a reptile like a green Iguana.And also, what South American species can fill up the two newly empty enclosures. I was thinking rock cavy for the aardvark enclosure and guinea pigs for the aardvark seperation, but there's no South American otters in European zoos apart from the giant otter, which I think might be too big for the enclosure (Though maybe they can be placed alongside the capybaras? Or otherwise in the pool of the big waterfall, if I add some land parts)
Would a crab-eating raccoon work here?
For the shrew and tortoise yes it could be possible to mix the tortoise with the tortoise exhibit you had planned, the elephant shrew would need a new exhibit though maybe where the bushbaby was.
