Mono for Unreal Engine now that it's open source

Is there anything keeping us from using C# with blueprint calls to allow for a C# on Unreal now that Mono is free and open source? I know there was a push back against the Mono-UE project while it was attempted as a paid version but now that it’s open source is this something that could be supported?

I understand it would only work for blueprint functions, but personally for a C#/C++ developer like myself it would allow me to mostly work in my preferred language of C# and still let me get low level C++ access if I ever needed it. Honestly after dealing with Unity and some crippling bugs it sounds like a dream.

Go on and help out with this. GitHub - raaffc-old/klawr: A set of Unreal Engine 4 plugins that enable the use of C# (and other CLI languages) in game projects targeting the Windows platform.
It is still very very buggy, but i made it work with the current unreal engine version.
There is a lot to do to even come close to what you see in Mono for Unreal.
