Hard to say.
I'm not sure an outline for that story ("Japan Triumphant") was even submitted, and I'm not that familiar with Star Trek: Phase II
. I believe I have an outline indicating some post-season two story ideas which describes the episode idea further, but I'll have to wait until later in the week to find it.
And, a Spock-less, Kirk-lite, TMP aesthetic (but with a lower budget) series run by a Roddenberry who had already begun to lose perspective? Nah, I'll take the Berman series and the Abrams films over that any day of the week.
