Just to clarify on this. I was meaning the North West has got the short straw compared to other operators who have received EMUs in the past few years, not compared to all areas
As I've said though, when West Yorkshire got electrification (twenty years before the Lancashire scheme) it got cascaded EMUs from Greater London (the old class 308s IIRC, with one coach taken out of each unit).
Over time the services proved a success and "earned" new stock, then later on were rewarded with additional coaches too (the 333s were three car, but extended to four car as passenger demand rose).
The same arrangement was going to be the case for the GWML lines west of Maidenhead, with 319s taking over from 165/166s (were it to go ahead).
Realistically, this seems to be what's planned for Lancashire. You also have to bear in mind that the availability of a large number of four car EMUs in the next few years is one reason for the scheme getting the green light. If they weren't going to be available then the cost of the scheme may be too much (needing 30+ new EMUs to be built may be too much to swallow)
Also, the Airdrie - Bathgate electrification isn't getting new EMUs, its getting units cascaded from the Ayrshire lines. From memory the EMUs used on the North Berwick line were "cascaded" ones too?
So not really a case of "Lancashire gets the short straw", more a case that most/ many electrifications
outside London mean cascaded EMUs. Whilst Crossrail will get lots of shiny new units, I think comparisons with other "provincial" electrifications are more relevant to Lancashire.
No need for 3 and 4 and 5 car units to be built. A build of 2 and 3 car units with corridor linkers allows formations of 2, 3, 4, 5 and 6 cars to run and allows extra flexibility over all 4 cars. For example, a service scheduled to be run by a 4 car unit would likely be cancelled if the unit fails, but if it's 2x2 cars it allows for it to be run short-formed. It would also allow for more flexible maintaince schedules and less need for some of the quieter off-peak trains to run as 4 cars.
I see your logic, but EMUs don't seem to be getting built in two coach size (correct me if I'm wrong, but I can't think of many modern examples).
You'd also need space for twice as many cabs, twice as many disabled toilets, twice as many wheelchair/cycle spaces etc etc in a doubled up unit - one reason why I don't think we'll ever see a direct repalcement for 153s.
Three or four coach EMUs seem to be where its at. Ordering new two coach ones may be more expensive (per coach).

If you want a Liverpool service from Piccadilly without using 13/14 there is another possible route. Piccadilly-Stockport-Altrincham-Northwich-Runcorn-Liverpool
No real need when EMT run Piccadilly - Liverpool.
I can see the attraction in the Stockport - Northwich - Liverpool service, as I think the Cheshire towns are ripe for a quality service
The above could also be speeded up by around 20 minutes by linking the Airport line to the Mid-Cheshire line which would then allow Piccadilly-Airport-Northwich-Runcorn-Liverpool as well as services like Llandudno-Airport-Piccadilly-Hull
This really needs doing. Manchester Airport is a great boost to passenger numbers, but a real drain on service flexibility. If it were possible for services to run "through" there then there are a number of new routes that could be investigated.
In another world, Manchester Airport could be like the northern Gatwick (in railway terms) - a busy Airport station which is also an interchange between different lines and a "hub". Instead we have something like Stansted (in railway terms) - a black hole of a branchline which doesn't permit any through running (without a major time penalty for reversing)
