The appropriate solution for the Chilterns is a Dutchified timetable to Moor Street when punters pick up HS2 services to the north from Curzon Street. 1.5 hours at 160km/h plus the rest of the way at ~300km/h at a half-hourly frequency for most destinations is a high-quality journey by any European standard.
In theory it is, but people won't do that. In the UK most people prefer to drive to a station for a direct train to their destination. This is largely because of the unreliability of connections.
See also the not insignificant use of Wigan North Western by car from the areas north of Liverpool despite it theoretically being just as easy to take Merseyrail into Liverpool and change there.
