Despite the similar name, the 84+CE is wildly different from the monochrome 83+/84+ calculators. Not only would many of the standard library commands need to be redesigned, but the compiler itself would need of lots modifications, if not a rewrite.
I've had ideas of doing such a thing, but it's a massive undertaking. It took over 5 years for Axe to get where it is today. So at least for the near future, the answer is: no, Axe won't run on the 84+CE.
