Modest-py python library for FMU parameter estimation using FMPy library instead of PyFMI library

Question

I am using modest-py python library for FMU functional mockup units parameter estimation.

By default modest-py is using PyFMI for handling the FMU files.

I need to use FMPy library inside of modest-py to do the same, in other words swap the libraries.

Here is the corresponding issue on GitHub.

Probably it can be solved by smart applying the adapter pattern, but I do not see how.

Has anybody done it before?
