Young actors will work for peanuts.
Last I heard, S31 was being retooled as a movie.
Could work as a standalone movie. Or possibly a mini series.
I'd probably watch it if Michelle were involved, but other than that I can't say that either the S31 series/movie or the Starfleet Academy pitches particularly excite me. I'd rather they just spin off a Titan series from Picard - Keep Shaw/Seven/La Forge and stay in the TNG era. The 32nd century really doesn't appeal to me at all.
