On a 4 car train, there are currently 8 cabins. You need 2 at least (have to be able to reverse a train in an emergency, from the other end). So you could in theory take out 6 cabins, and add 12 more standing bodies. Out of 240 passengers.
A 5% capacity increase, at the cost of incredibly reduced flexibility - cars couple and uncouple all the time - as well as increased cost because now you'd be designing several models of car. Doesn't seem worth it to me.
Also, the Buffalo design is the only one worth doing.

If you take out the cab, you could probably add much more than 2 people standing per cab. Probably 4-6 seats plus a couple of people standing.
If you had 50 metre car instead of 25 metre cars, you could also have people in what is currently the space between cars - probably another 10-15 people.
If they bought consists that were 100 metres long, had cabs only at either end, and were continuous inside, you are probably adding 10-12 metres of length of usable passenger space over what is existing, approximately half a car's worth.
However, if we get 60 cars for the price of 50, that helps a lot too. We're going to need another 60-80 new cars in the next decade on top of this to be able to go full time 4 car trains with all trains on all lines, and to be able to retire the U2s that need to be retired.
By 2020 or so, we are going to have to start thinking about retiring the oldest SD160s too.
