Absolutely love the idea. Not big on the story.
The tone also changes a lot. The beginning part of the story starts off raunchy, but once we get to Lucky joining Lucy's household, it becomes serious and touchy-feely without a lot of humor.
I don't feel the tension of an A story throughout your script. It just moves from one story to the next. At first, we have the pregnancy, and then we move on to what I think is your attempt to build a conflict between Walter and Lucky. It seems you solve their riff once they go fishing and with the robbery, but it doesn't naturally open up your next story of the wedding.
Should we open another door once one door closes? Absolutely, but don't force it.
Now we arrive at Lucky walking out on the wedding. While I believe that's related to the pregnancy, it doesn't feel like it with the way the story is written. It feels like a separate obstacle. The script moves from A story to B story to C story instead of an A story that encompasses a B and C story.
