Sure, but why should it be accomplished without Pony? Languages are optimized for use-cases. This means that some languages are good and some are worse at handling particular use-cases. If Pony is the best choice for their use-case, why would you not choose it? Taking all the risks of a new tech into account, of course.
This could be accomplished without using Pony, unless you view "Wallaroo's architecture" as being effectively synonymous with "use Pony."
