I did some research and found out that Minecraft PC Version is coded in Java and Minecraft PE is coded in c++. If I was to get access to the mods coding by the author, could I use a converter to change that programming from Java to c++ and then somehow implement the converted programming into MCPE so I can use that mod on it?
I don't think that's possible. PC mods have a different structure than PE addons and the PC version's code is different from PE. Even if there is a way, you would be better off creating C++ mods from scratch.
