Yes, Kristian Reitveldt committed an adjusted copy of the ATSUI module as a CoreText module. I haven't actually tested it, so I don't know how well (or even if) it works, and Kristian intended it mostly as a starting point rather than a finished product. (I only know because the original changeset broke the build and I wound up improving the italic font synthesis code a bit... but I don't have any deep knowledge about how layout works.)

I don't know that the ATSUI module can handle Arabic. You should probably have a look at the code, and then send any questions to gtk-i18n-list where there are folks who actually understand how pango works can help.
