I think that it is going to be easier (once you get the hang of it). When 
I started reading mkii code, I understood the steps that were being 
followed, but the fine details were pretty hard to understand. With 
luatex, the broad steps are still in tex, so that part is the same, but 
the fine implementation (that needed a real programming language) are in 
lua. This makes it much easier to understand. I could read the new mkiv 
pretty printing code and see what it was doing. With the mkii pretty 
printing  code, I spent about a week and was still clueless (rather, I 
understood bits and pieces, but there was no way I could extend it to 
another language).

I think that this is enough to overcome to compensate for the overhead 
between going back and forth between lua and tex code.
