If there was a Merseyrail service to Warrington Central or Birchwood every 15 minutes all-day, with the option of a quick change to either a CLC fast service (perhaps 2 fast trains per hour), or a stopping train into Manchester (assuming they ran every 15 minutes too), would this be a deal-breaker for you as a commuter ?
Yes, and here's why:
I live 7 minutes (5 if I'm late) walk from HNX.
Currently it takes about 22 minutes for an all-stations train to get to WAC, and about the same (24m) for a fast train to get from WAC to MCO -Data taken from RTT for this past Sunday.
That's already a 46 minute journey on trains alone (for comparison the stopper I used to get out of MCO in the morning took about 50m-1h for a MCO-HNX run)
Adding in a 5 minute "quick change" that takes the time "in the system" (not counting to/from stations) up to 50 minutes - already as long as the stopper, however on the stopper, I could get a seat (more often than not a table), pull out a laptop and make use of the 2h/day that would otherwise be idle which having to pack up and move 20 minutes in throws out the window. The only time I've been able to get a seat on a fast is the old TPE 2210 off MCO towards Liverpool so I wouldn't be hopeful about getting one after having to change onto either the Norwich or Airport train...
With all that taken into consideration, it's something in the region of 1h minimum door-door. Off-peak I can drive from my house to the City Centre of Manchester in about 30-45 minutes, in rush hour this goes up to 1h-1h15... so a decent amount of times it would become a genuine consideration of whether I want to be able to work on the journey or get there quicker (and even then, breaking at WAC would spoil the whole working bit).
In short, whilst the current through stopper is slightly slower, a seat and laptop wins over changing and getting the express.
And for those noting my omission: I realise that the new Airport service (at least on the current timetable) stops at my local, seemingly answering my prayers, however would it continue to under the great hiveminds plans to Merseyrailify everything?
Now, what I would do with crayons fully locked and loaded (given that's the type of thread this is) would be (in one direction):
1TPH Fast Manchester>Warrington, then stopping to Limestreet
1TPH Slow Manchester> Warrington, then stopping to Limestreet
1TPH Fast Airport>Birchwood>Warrington>Widnes>Limestreet
1TPH Norwich>Birchwood>Warrington>Widnes>Limestreet
1TPH All Stations
With appropriate passing loops to let the fasts overtake the stoppers.
