For Crossrail it would presumably be via Tottenham Court Road, but I
have no idea how convenient the interchange there is going to be.

From the Northern Line there will be link stairs between the NL
platforms taking people down to a lower level where there are more
stairs down to Crossrail platform level.

So not stepless?

This is at the same level as
the main escalator shaft down from the enlarged ticket hall.

Sorry, which level is that - you've described several.
