Euston is the only sensible destination for a north/south HSL, in
simple geography and engineering terms. A link to HS1 to allow NoL
trains (which might be viable at 350km/h) would be sensible. Maybe a
travelator to KXSP...

Exactly. A branch from Heathrow to the HSL (in the Denham area, if the
Chiltern corridor is used) would make sense (as suggested by Greengauge),
but running the HSL from Euston/St Pancras to Birmingham via Heathrow is
likely to be too slow, and certain to be too expensive, to be worthwhile..

Additionally, if space is tight at Euston then the whole station could
be rebuilt with longer platforms at the current level stretching to
buffer stops just north of Euston Road (or at least north of the
course of the Met & Circle lines) and with the station concourse being
on the next level up above the platforms. A mighty expensive project
of course, plus the main Underground concourse might well be in the
way of all this subsurface shenanigans, but that's not an insuperable
problem.

For local distribution of arrivals Euston Square station needs to be
moved. Or, Euston Square should be linked to the mainline and tube
stations by a travelator.
