"They" could have done all sorts of things, if the cash
was available. Are
you looking at this from a 1960s perspective or a 2000s
one?

Why would it have cost more to run larger trains? The
difference in tunnelling
costs would have been negligable just to make the tunnels a
foot or 2 wider.

Width isn't the main issue, it's height. In case you hadn't noticed Met and
District trains are taller than those on the Piccadilly and other deep level
tube lines.

A Piccadilly Line train is only 211mm narrower than those on the District.
They are however 711mm shorter.
