What would it take to make this work with libreoffice as well?

While the difference may be so great that it would make more sense to start from scratch: What would it take to make pycel work with LibreOffice Calc?

Dont think there would be any fundamental difficulties. It would just be finding a suitable library that can extract the formulas/values and wrap it under a common api.
