Farmbot + Agrokruh?

Not sure if this belongs in Feature Request or Hardware or somewhere else - mod please move if in wrong sub.

Anyways I was looking at using the Agrokruh or Agro-Circle style arm to work a larger field - may be getting in to a 5 acre parcel and this type of setup looks good in scale for the area. Would it be particularly difficult to get this the Farmbot system working on polar rather than cartesian coordinates? I’d rather utilize all the fine work that has been achieved with this project in terms of software engineering rather than get bogged down trying to work through all that from scratch, and a coordinate system conversion seems like a small building block of work in comparison to the rest of the programming. Would there be any interest in collaborating on a project like this to shoot for medium-scale agriculture?
