These are just my thoughts. I doubt any traction could be made on these ideas, but in a perfect universe, I'd love to see some these implemented:
--A salary floor. Make teams pay "competitive" salaries and get more competitive teams as a result (maybe? Hopefully??)
--A salary cap is NOT ever going to happen at this point. I would settle for some actual damaging punishments for those teams that do go over the supposed luxury tax threshold. And I'm talking DAMAGING: 1000%+ penalty per dollar (?) over this threshold. Plus automatic loss of draft picks, starting with a first round pick for even $1 over the threshold, a second rounder once you go over $1,000 over the threshold, a third rounder if you go over $10,000, etc. etc. Just make it REALLY painful for a team to be paying so much money to players.
--Revenue sharing of TV/radio/Internet money. I would also be fine with MLB taking over all broadcast rights themselves and sharing the money that way. Team-owned broadcast channels would go away.
--Have all players worldwide subject to the MLB draft if they want to come to America and play in the MLB.
--Get rid of the deferrals. Immediately. No grandfathering in, either. Sorry, Dodgers, you'll need to start paying Shohei and everyone else their actual salary each season.
--Perhaps get rid of arbitration and make free-agency start after 5 complete MLB seasons.
Again, I am perfectly well aware that probably NONE of these things would be agreed upon. I bemoan the likely fact that MLB could shut down in 2027, just when more of our Brewers prospects should be up and strengthening our team. And if baseball were to disappear for an entire season (or longer?) how many fans will they lose? Would the revenue streams that the owners/players depend on in today's game even exist in 2028 or 2029 if the fans say, "heck with it, I found other things to do with my money instead of giving it to you" ?
I, myself, will always love baseball no matter what happens. I might not go to as many games, buy merchandise, etc. but I'd still pay attention and hope that they can get things fixed.
My worst fear is that nothing is really accomplished and they sit out for a season or longer only to sign an agreement for 5-6 years that really accomplishes very little or nothing.
