If the Bank of England sacrificed its vaults (Very little use for them
now, with the gold sold off) and Cannon Street St was put underground
(Plus a new tunnel under the Thames), would a tunnel connecting
Moorgate and London Bridge be feasible? Or do the tube lines around
there make it impossible?

I'd be more interested in the feasibility of turning the Northern City
into a DLR line to East Finchley... the tunnelling would be much
shorter (but again with vault issues), and then the DLR could take
over Moorgate-Finsbury Park-Parkland Walk-Highgate HL-East Finchley.
Divert existing Moorgate services over TL3K to South London (hey, the
313s are ideal for that job) -- and if they take the Elephant route
from Blackfriars, you don't even need to do TL3K: the northern half is
being constructed as we speak as part of the CTRL works, even if it
isn't due to be used for ages. Providing we can schedule enough trains
over the junction at Blackfriars, we can take over routes like
Blackfriars-Catford-Sevenoaks and possibly even divert some Victoria
trains to run instead to Welwyn/Hertford.

It would be nice to run the DLR all the way on to Mill Hill (or even
via Mill Hill to Edgware!), but track-sharing and/or grade separation
issues might stymie that.
