Do you mean return of the House of Lords to 1959-1998 existence? That is pretty much impossible unless dictated by an ASB. No piece of constitutional legislation in British history has never been repealed outright, and this is going back to the Middle Ages. Maybe the 1660 Restoration comes the closest.
As usual with this type of legislation, further changes were envisaged at the time, and keep getting proposed since, but they are all in the direction of making the chamber more democratic, even the Tory proposals.
