Very rare indeed. I think there's only been a handful of occasions when the national presenter has joined the News 24/Channel presenter.
Only ocassions I can think of have been the above with Gavin Estler and Michael Buerk, an Azores summit news special with Huw Edwards joining Jane Hill on the News 24 set.

The 2000 TVC power cut with Darren Jordan presenting alongside Carrie Gracie from the old Westminster newsroom set.
When Colonal Gaddafi was captured with Mishal Husain joining Jane Hill in N6 (although Mishal was on a World News shift at the time, I think it still counts).

I haven't counted Peter Sissons and Chris Lowe in the mix as they became dedicated News 24/Channel presenters post their time fronting BBC One main bulletins. Although, come to think of it, did Sissons also present the weekend BBC One update simulcasts from N8? I can't really remember?
I think there might have been a few occasions around 2007 when the likes of George Alagiah and Sophie Raworth did stints on the news channel in a bid to increase the high profile names on the channel. I also believe, but correct me if I'm wrong, but that was also around the time Huw Edwards started presenting his BBC 5 O'clock News hour (as it was then).
Nowadays you'd just get the World News presenter joining the News channel presenter or vice versa.
George Alagiah and Maxine Mawhinney also presented News 24 together at the start of the Iraq War:
There was also the occasion when Saddam Hussein was executed and Peter Sissons joined Ben Brown on the News 24 set (although I'm not sure if Peter actually still was a network presenter at this point?):
At the time (circa 2001) Peter Sissons and Michael Buerk were considered the top BBC1 newscasters. But on News 24 and World, Gavin Esler and Nik Gowing held a similar status. They would always be called in if a major story broke. Like deejay says, it doesn't seem to exist anymore for the continuous news channels. Remember, back in those days it was very, very rare for any simulcasting to go on outside of overnights. So News 24 and World had their own pool of presenters who were largely unknown to each other's viewers.
Of course, it led to the occasion in the wake of 9/11 when Michael Buerk presented alongside Gavin Esler on the News 24 set! That was an incredible rarity!
EDIT: In fact, I uploaded a video of it several years ago. It's an old-style Real Player video file but it's playable in VLC media player if you have it.
