That's what I was thinking, although the lates ABC dictionary, the
Comprehensive, no long uses the CASS table but KangXi with extensions to
handle simplified characters. The order of the CASS table used in ABC
also differs from the most recent editions of the Xinhua Zidian and
Xiandai Hanyu Cidian. However, I think once characters are mapped to
the 189 CASS radicals, switching around the order would be easy.

I've been working on a program like you describe. I think it will
handle the majority of characters, but in a significant percentage of
cases the mapping is not direct and will need to be hand-corrected.

I'm not sure and I'm not an expert, but from my experience it seems so.
