the south that will probably work , for the north it won't. If it
terminated at Finsbury you'd have the piccadilly & victoria line
catchment areas plus the whole of the east coast main line who could
switch to the ELL there. Instead they'll all pile on the victoria line
for one stop. Terminating it at Highbury is a poor solution and smacks
of treasury cost cutting.

You're forgetting the Northern City Line, so all inner-suburban
services also call at H&I (except at weekends when it's closed, but
that's a separate issue). That means the only ECML passengers needing
to use the Victoria Line are coming from Potters Bar and points north.
For Piccadilly Line passengers the switch to the Victoria at Finsbury
Park is so easy as to be non-existent, though the overcrowding is a
fair point.

OTOH, going to Finsbury Park requires 8 movements on the flat every
hour across the NLL freight lines, which doesn't sound viable to me.
