They wouldn't send London-York or London-Newcastle traffic via Manchester.You've still looking at a section of railway which has to take every fast train from London, Birmingham and Liverpool to Manchester, Leeds, York and Newcastle.
If it were 360kph all the way, the maybe. (I'd need to work out the timings.) But the four-track transpennie route via Huddersfield won't be fast enough.
