Hi,
I used GhC_Python to use these libraries in gh, and it works pretty well ! It just has some trouble outputing gh format data (lists, trees). The workaround is to put a classical GhPython component behind to get the right format.
Other options include Rhino Inside CPython (needs Rhino 7 WIP) and Rhino3dm (limited capabilities) , possibly combined with rhino compute for the good stuff
So this means basically no? I guess the Rhino Inside approach is not suitable if you want to combine it with Grasshopper as it just allows you to work with Rhino Geometry.
