Heathrow needs a through station with intercity services. Anything else

Instead of, as I understand it, no mainline (as opposed to tube) trains
that even manage to stop at all 5 terminals without reversing - we might
even get 3tph each to T4 and T5.

I would say there's a case for 8tph to KHR, half continuing to Staines
and half to Uxbridge.

And they should bite the bullet and divert all GW mainline expresses
through Heathrow. How would the length and cost of this diversion
compare with the Selby diversion?
