For the 10'o clock thing...
Build a small video screen next to the main studio about 1m wide with the same graphics as the main studio screens
At the end of the 10 on beeb 1 - "..across the UK" The sting for the 10 would come up and at the end it just zooms in on the desk in the studio again but (possibly) with the N24 graphics (the ones they used when N24 moved to the 1,6 and 10 studio for a weekend last year) not sure if this could have the same presenter as the 10 or a different one, then a presenter walks over to the tiny video screen and gives the headlines live at the end of the regions. It wouldn't be that hard
