Putting aside the question of whether Star Trek should come back to TV (the topic of many other threads), I think it's a terrible idea trying to get a network to do Star Trek.
Star Trek has never done well in the long-term on a network. NBC cancelled TOS after one year and only kept it going because of fan pressure. They gutted it in season 3 and put it in a suicide time slot - they didn't want to keep it.
Voyager barely survived its seven years and frankly we have Jeri Ryan channeling the spirits of Emma Peel and Wilma Deering to thank for that. Ask the average joe on the street to name a character from Voyager and they'll name Seven of Nine. No one will give you the name Chakotay unless that street happens to be outside ComicCon.
And it's a miracle Enterprise lasted as long as it did, taking only the ratings into account.
However, TNG and DS9 thrived in first-run syndication. We didn't have people worrying week after week about ratings numbers. No one cared if American Idol was up against it. And funnily enough TNG (not so much DS9) really entered the public consciousness in a way Voyager and Enterprise never did. All through syndication.
Network TV is in my opinion in its last decade of viability. We're seeing the cracks starting to show in the hull with NBC's meltdown. Two networks have already collapsed and needed to merge in order to survive.
If you're going to insist on trying to get Trek back on TV, in my opinion interests would be better served in focusing on either cable outlets like Syfy (lots of people hate Syfy but they did give us the new BSG) or channels like AMC. First-run syndication is pretty much dead except for a few oddballs like Legend of the Seeker (which gets shown at 2 AM on the channels I receive where I am). But cable is thriving and that's where Trek should go if it comes back.
Budgets aren't an issue. Doctor Who lasted for years on a $1.98 budget and even today its budget is less than most US shows yet it manages to come up with cinema-quality stuff most weeks.
The ideas are great, but IMO approaching Les Moonves with it is the same as someone trying to approach Michael Grade about doing Doctor Who. DW would never have come back under Grade, and likewise I do not believe Trek (even with the movie being a big hit) has a friend - in terms of viability as a TV series - in Moonves. Not everything has to be produced for CW or CBS, just as not everything made by Fox has to go on, well, Fox.
