Hey Deryck,
fascinating work, inspiring project! To think that you are working on this particular clock in the tradition of historical clock makers... and that you are facing the same question about lunar anomalies that astronomical clock makers faced since the earliest days... and to imagine how they, back then, conducted their research and contacted astronomers...
I'm not the person you're looking for - but I used to be a scientific librarian and still have some skills to find at least preliminary literature for a given question.
This article, especially page 3 [or 72 in it's original publication], describes historical and current algorithms for machining lunar anomalies into astronomical clocks.
While this article is in German and not so useful, probably, it's author is a physicist, author of astronomical books and newspaper articles -
AND he is a translator of articles and books. So it's safe to assume you can converse with him in English, directly.
In the right bottom corner, click on
"Kontakt" under his picture to email him.
The PDF linked to above is about the astronomical clock that was built in Germany by Hans Scheurenbrand in the early 2000s.
Hans past away in November 2015 so we're a little too late to contact him directly. He wrote a
book in German on his clock work - probably available through international lending at a scientific library in Australia. (Note that Hermann-Michael Hahn is co-author on the book, too.)
Lastly, if you would like to open a thread on an astronomy forum with a much bigger audience, try this

Totally intriguing web page, too!
Cheers Annette, now living in Rostock, where the
astronomical clock in St Mary's is being wound up every day since 1472...
