Jon,
It should actually be very easy to create such a thing. This is something I have requested as far back as 6 or 7 years ago for Transcript (I was using SC back then). I was told that Keyed Arrays were coming and would solve all my problems... think again. It is no different than having a CPU and a separate vector processing unit in a chip. The main way to go about it, is to be able to allocate a fixed amount of contiguous memory to an array of n dimensions with n byte elements of a fixed type. The language needed to process it would be very simple set of conditional and repeat and math operators that have a direct equivalent to the usual machine code operations. It would be trivial for a compiler writer to create the machine code, or for that matter, a simple compiler could be written in transcript and with just a minor speed penalty, the compiled code could be machine independent byte codes with a teensy-tiny runtime package for each platform. It would run at least ten times faster than Transcript.
Is there any reason that a large array of data could not be sent to an external along with a set of "bytecode instructions" for processing the array?
It would be great to have it as a built in function for everyone to use, or an enterprising Rev developer might make an external add on. I would do it if I had more experience and time, but the last time I wrote something like this was 30 years ago for 6800 machines. It was a tiny universal "Machine Code" and compiler.

How hard would it be to create a math and array processing external for RunRev?
This would be useful for numerous things, including complex image processing.
It would need to do two things: 1) allow the user to pass a script (like in C) for processing the array to the external
2) send the array(s) itself to the external, which then uses the previously sent script to process that array(s) and return the result.
