I'm going to invite my D&D group to see the movie, rather than go on my own in quiet shame. And we're probably going to remain a D&D group, even if that never involves 5.5.
I'm also going to keep working on my 5e clone. I will say the prior floated offer of just the core rules section of the SRD in creative commons gave a much clearer (albeit difficult) path of what I had to do to create my own not-D&D, and gave cloning a clearer purpose. But it is certainly all easier now, and trying to maintain various levels of compatibility got much easier.
