They could feasibly get one of the hybrid pairs going around, if the Sumatran program goes well.
I think it has the potential to be an excellent small zoo. Don't really like the layout though - and they could be maximising their space better too. Why not combine the giraffe, rhino, zebra and ostrich paddocks into a single exhibit that could be the centrepiece of the zoo? They don't appear to have huge amounts of land to work with, so keeping what appears to be a fairly strict one-mammal-per-exhibit layout is a bit strange.
Barbary sheep and dromedary, water buffalo and blackbuck could also be mixed exhibits. I also really dislike the finish being with domestic species - horses, pigs and guinea pigs. After orangutans, lions, giraffes and rhinos, a stronger finale than a few farm/pet animals could be hoped for.
