I actually think that these copyright concepts aren't particularly automatable, and even if we try, its pure arms race.
And the merger doctrine isn't the big problem here, it is the more complex analysis where merger doctrine clearly doesn't apply that needs analysis and I suspect the analysis is difficult to (even partially) automate.
But I'm looking into it.
