If, as Philip suggested, 48 units (lets say 22x2 and 26x3 car) were used on 40 diagrams, then the minimum number of 2 car diagrams would be 6. (26x3 car, 8x4car, 6x2).
That's few enough that they could be kept away from the cities at peak times, maybe with some shuffling during the day if diagrams are busy in the morning but not evening and vice versa.( Which would potentially mean most 2 coach trains going around alone off peak)
However, that assumes no Northern Connect service would be longer than 4 cars. That might be an issue on some routes, especially if passenger growth continues throughout the franchise. If longer trains are needed anywhere that means more 2 coach trains somewhere else.
Has anyone worked this out for the rest of Northern's fleet? Is it any better or is 2 cars going to be the standard train length save a few peak services?

The problem with the Barrow services will be that, despite the more spacious alternative trains, they will fill with passengers for Preston (and Wigan if they stop there).

Manchester Airport to Barrow will be served for the most part by the Scotland service, if 195/0s are to run in single formation at all then I'd think Barrow and Lincoln will be the first choices to allocate them on.
