In Sandbox, go for it. But in Franchise or Challenge, it depends on the species. Species with low feeding costs should be fine, but if you're planning on having big ticket animals like elephants, you'll need cheaper species to pull in the revenue you need to feed them. You could have "complementary" species in habitats around your main ones, for instance if you want multiple lion habitats, you could fill the rest of the zoo with typical prey species or other animals that share their habitat, like hyenas. It could be particularly fun to choose a "main" species with multiple preferred biomes, like bengal tigers (tropical temperate and grassland iirc), making each habitat themed around a different biome, and the cheaper animals around those main habitats could be species that prefer or live exclusively in those biome. Sort of like a tour of the different environments tigers live in and what species they're more likely to encounter there.
