The hard part when making a virus is to exploit the target system to run said virus. And if you have such an exploit, then supplying a compatible binary depending on which OS the target system runs is easy.

Exploit attempts for embedded systems (routers, cameras, etc) typically start with attempting to execute code in a portable language such as Shell scripts (which would be the only thing this new project would replace), those scripts try to detect the architecture of the system and then download the appropriate binary (the server hosting the malicious binaries provides many variants for different architectures).

In the end I don't see this solving a real problem when it comes to malware - this problem has already been solved through other means.
