I like the idea and would be one of the Programmer who would like to do that 
but I don’t think you get it organised or this question is picked up by anyone. Maybe in the Forums would be a better place. If it would get some traction, I would also sponsor a portal to organize this micro jobs and payments. But just to be said, I guess you talk about thirdparty plugins/libraries not Engine Modifications, because this is a thing epic is quite picky. I mean look at the pull requests on github…sad…sad…
