As someone who had to work in ArcGIS using their C++ COM, their java, .NET and their python implementations for several years can I strongly urge you not to do this? Why? Well, things that worked in one language, wouldn't in others. Bugs where we had to work around one way, had to be worked around another. The fact that the API had "get_Foo", "GetFoo" and "getFoo" methods all in different classes should really give you an idea. The library was awesome way back when it was cutting edge but from using it, I'd wager that it was developed by different teams, staffed with different resources, all made to work under different deadlines.
