You probably wouldn't get much of a speed-up anyway. The overhead from executing 42S programs is quite small, particularly when compared to CPU-intensive floating-point calculations.

The most effective ways to speed up that demo are: (1) plug in a USB power source to increase the CPU speed from 25 to 80 MHz, and (2) compile native code with single-precision binary floating point, which the CPU supports in hardware.

Of course (2) also requires extensions to the Free42 part of the firmware, to add support for loading and executing native code objects. Or some even more drastic change, like ditching the DM42 firmware altogether and running a minimal Linux instead.
