I'd hate to see what the in-car track diagram would look like, though!

Presumably they'd do as they do on the District/Circle lines and have
some and some, according to which destination the particular train
normally served.

Or perhaps, as with the Met/H&C/Circle in the early 1990s, the 'new' branch
would have been badged as a line in its own right.

That would have made the most sense, especially with the absence of
Edgware+. Trains running - "on paper" - purely as Finsbury Park to
Alexandra Palace or FP to Edgware would create an elongated Y-shaped
line, with only minimal track-sharing between just south of East
Finchley and just north of Finchley Central:

Although obviously feasible, I can see less of an imperitive to run
High Barnet to Finsbury Park, since both Finchley Central and East
Finchley have plenty of platform capacity for interchange, although
that doesn't rule out "peak hours only" services during the rush hour.
