It's too bad that there weren't better writers for Geary's final years with the show, writers that could have done justice and given a proper closure to Luke and the pairing of Luke and Laura.

They wanted to do that. Tony explicitly rejected it (and apparently loved the whole killing his parents thing). There were many problems with the writing in 2012-2015, but their first order of business was reuniting LNL and it was one of the first plans Tony killed (along with addressing Luke's alcoholism, which he subverted as they begin dealing with it by ad-libbing taking drinks at the Q mansion onscreen instead).
