Re-implementing CubismNativeFramework, is it allowed?

Hello, I'd like to ask question about Cubism 3 SDK for Native.

I'd like to use Cusibm 3 SDK for Native to render Cubism 3 models using LÖVE framework in conjunction with Lua (LuaJIT) language. Due to performance reasons, creating Lua C binding of Cubism Core using Lua C API is not allowed, but using LuaJIT FFI (Foreign Function Interface) to load Cubism Core DLL/shared object is okay and in my case, that's preferred way to use external code that is in DLL/shared object. However this means I have to rewrite CubismNativeFramework to Lua because using Lua C API to bind all the CubismNativeFramework would took long time and it's not allowed in the first place due to performance reasons.

My question is: Am I allowed to rewrite CubismNativeFramework to Lua? And once it's done, am I allowed to open-source my rewrite of CubismNativeFramework?
