With investments, there is quite a bit that could be done. The signalling system is outmoded, but replacing it will take years. Reconfiguring Rogers Junction would increase capacity. This has been proposed several times in the past, but the MTA couldn't get funding for it. I believe there are long-term plans to connect the Flatbush Avenue terminal to storage tracks nearby, which would increase the throughput of the 2/5 lines. Those are the major items that make sense. Other ideas, such as extending the platforms or widening the tunnels to IND dimensions, don't seem to be practical.

The 4, 5 and 6 are all at their physical capacity.</i> I doubt that. There are mornings where everything flows flawlessly and the 4/5 trains arrive in the station every 3 minutes. There are others where the trains come at best every 10 minutes. This may be a problem with people loading and unloading, signals, etc., but these are problems that can be fixed and therefor have a significant increase in capacity.

The MTA has been talking about it for quite a while, but as noted, they first had to finish the signalling improvements. Indeed, I suspect the MTA deliberately timed the report card so that the L would get a failing grade. Then, they could say "We heard you," and add capacity that had already been planned.
