Mixing species is never a good idea with amphibians of any kind.

I'd say no for these guys. Some frogs are okay with other species, but White's have voracious appetites and will go for anything slightly smaller than themselves, and perhaps even bigger.

Mixing with any species of frogs is dangerous. There is absolutely no way we can mimic their environment accurately enough to mix species safely. The micro-habitats alone vary greatly just a foot off the ground in the wild, and we can not duplicate them no matter how hard we try or how large of an enclosure. It's not just the size of the animals or predation, but stress is also a large factor when attempting mixing, as well as frogs from different locals have different immunities from things like parasites. So even though they might be similar in their needs, there are many other biological differences in each locality.
