i'd be surprised if this scheme was actually successful.

its very difficult to relay signs from the dugout to the batter in the few seconds between when the sign is given and when the pitch is thrown.

base runners on second base have always been able to see the signs between pitcher and catcher and relay the information to the batter. To counter this catchers use a complex combination of signs that change inning to inning, sometimes batter to batter.

I don’t think the camera room were relaying the signs, but rather what the signs meant. So that when a base runner was at 2nd they’d understand the signs they were seeing.

Not sure. Batters already look back to the dugout sometimes in order to know if they want a bunt, squeeze play, hit and run, etc. That doesn't take more than 3-5 seconds. If they already coordinate some kind of sign between the trainer (in question) and a player, then it shouldn't take any more time.

The catcher throws the sign after the batter has taken his stance. No more looking at the dugout.

3 seconds is more than enough time for the pitcher to realize the batter isn't paying attention and throw a strike. Batters will look of course, but they step out of the batters box (or otherwise - I don't know all the rules) to indicate that a pitch cannot be thrown now.

Once the batter is ready to receive a pitch the catcher can signal a new pitch.
