On a slightly different note is there any way that this gateline can
plausibly cope with a crush loaded East Coast train arriving or is this
just a plot to make train travel as unpleasant as possible.

Plenty of other stations are like that - a morning peak Shenfield train
coming into Liverpool St takes quite a while to get through the barriers.
I would doubt this would put Network Rail off at Kings Cross either.

And somewhat closer to home, a packed 8-car FCC arriving at Kings Cross
Suburban.
