Sorry but this story belongs in the "least amount of research done" category.
The H & M tunnels were built for 3rd rail rapid transit use only, and the curves will never allow standard size passenger cars (NJT and Amtrak) to pass through.
In fact back in the mid to late 1960's when the Port Authority started to put new PATH cars in service they had to make cuts into the tunnel curves just to allow these rapid transit cars to pass. This alone was not an east task as the sides had to cut so as to not risk the integrity of the tunnels. It is also very debatable if there would be room for overhead wire to be strung in these tunnels.
Lastly PATH trains do NOT share trackage with NJ Transit and Amtrak.
Yes, there is a section between Newark Penn Station and Harrison
where you will see all these trains near each other, but they are running on their own dedicated tracks, with their own signal and control systems.
Yes, solutions are needed for congestion in this area, but this option is so NOT possible.

PS: Good reply thoughts here...The track gauge is the only similarity between the PATH and what NJT uses on its commuter rail system...
To allow larger NJT cars to access the tighter clearances and curves in the Hudson Tubes (I will use that old name) the tunnels would have
to be either enlarged and/or rebuilt to allow NJT commuter trains to use them...I will add that these cast-iron tubes were not designed
to accomodate overhead wire - with 11KV AC wire you would need a sufficient clearance to allow the current from not "flashing over" to
either the car or locomotive roof below or the cast iron tunnel rings above...
The MBTA's (Boston) 0600 and 0700 series Blue Line cars are to me literally "PATH cars with pantographs" and I also know that the roof apparatus
and pantograph will not correctly clear the PATH tube clearances...If PATH used overhead wire these are what PATH's cars would more then
likely look like...
TL: That was a excellent post with the history of connecting separate rail lines in the past...With your mention the LIRR's Flatbush Avenue
Terminal comes to mind...To allow 85 foot cars like the M1 MU's to go to FBA there had to be modifications like higher levels for its platforms
and luckily the curved sections of track in the tunnels there did not preclude the use of longer cars - as mentioned the oldest LIRR MU cars
were IRT compatible and the original thought was to run through trains over the IRT lines to Manhattan - some of the remnants of the old
proposed connection were still visible until the recent years FBA renovation by the MTA...
In closing the price tag to modify the PATH tubes would be probably so high that it would pay to just build the two new proposed Hudson
River tunnels to NYP and renovate and rebuild the current two track tunnels when the tracks can be shifted over - one at a time allowing
three tracks to enter NYP eventually and then four when the project is finally completed...
