Abbey Wood is the end of the line. (Well, the Crossrail branch.)

Yes, so reversing the HEx2023 there will be easy.

Ok, leaving aside the fact that no such HEx service is going to exist.

It's a long time until 2023, nor do I see HAL dropping the brand quietly.

It might just have to sponsor and co-brand direct Crossrail trains from T5
to Abbey Wood. That would have the further advantage of freeing up four
paths per hour for 125mph trains on the GW main lines from airport junction
to Paddington.
