I don't think there's any need for 16 bit; pretty much all IoT stuff is either ARM (with quite a lot of it using v8 cores because you might as well) or ESP/tensegrity. The ESP32 would run a stack vm ok I suspect, just needing a well trimmed image. The tiny ARM machines could potentially even run a Cog vm when memory allows.

The combination I think would have some value is 32bit oops for '64 bit' machines, ie using the better instruction sets. On ARM it would potentially make a big improvement to run AArch64 code but stay with 32 bit oops. You are of course somewhat at the mercy of your OS to be able to run within a 4Gb address space and not get silly.
