Extension of Openfoam Adapter for hydrodynamics

Hi everyone!
In our research group we are dealing with huge co-simulation that now are being run manually. However, after some testing (reading docs and running tutorials) of this library, I do believe we can handle better our simulations with this software. Indeed, our simulations are not heated related but more like hydrodynamics and biochemicals processes, for instance Waste Water Treatment Plants simulations of their tanks.
Having said that, we need more variables to be added to the adapters support (lot’s of them e.g. viscosity, epsilon, …). Do you think is feasible to do that much extension of functionality? Has somebody tested that?
I’ll glad to read your opinions, as well as to provide more information if needed.
