the issue of terminating such a service at Euston - i haven't the
faintest idea what the approach to Euston is like; is there any chance
it could take 12 tph?

Unfortunately, it isn't, as the approach lines to Euston are shared with
Silverlink County services as far as Camden Junction (around 1.5 miles
out of Euston), and occasionally with Virgin departures from Platforms 1
to 7.

Ah, that's what i was afraid of.

12 tph of metro + not a lot of tph of county (7 in the peaks?) would fit
down those lines; the problem is that 12 tph of randomly-timed trains and
however many of timetabled trains would not - it would just shift the
interference problem from one place to another.
