If you split into two lines then the obvious split is Edgware-Charing
X branch, Barnet-Bank Branch because that would mean there would be no
need for the trains to cross at Camden Town.

In fact, the Bank branch route actually runs to the *west* of the
Charing X route after leaving Camden Town - so following your logic, it
should be EdgwareBank and BarnetCharing X.

However, it's a moot point as the trains don't need to 'cross' at Camden
Town - at least not in the sense that I suspect you are thinking of.
There are non-conflicting routes available which means that trains do
not have to cross 'on the flat'.

Have a look at Tubeprune's diagram;

Trains do have to 'cross' at present as both City and Charing X trains go to
Egdware and High Barnet/Mill Hill East. Splitting the line into Edgware via
City and High Barnet via Charing X would solve this problem.
