The pinch point will be if you arrive into the C gates. This is an isolated terminal currently relying on a bus to transfer everyone to the main terminal due to the train being closed.

This in its self is a lengthy process, even before you start the usual immigration formalities. If you can use Egates and your bags are quick up the belt then maybe you can clear the arrivals area within 45 minutes of landing. If you are first class, there is an expedited transfer from the C gates.
