If they move BBC One 'clock news to Salford, does that mean they could also have studio,  staff and newsreaders available to opt out of the news channel for any breaking UK only story?  On top of that if this works they could see addition uk only bulletin on the news channel maybe at 4pm using the same staff?

To some extent, it would theoretically allow for additional UK content, but only really in the same way that they could do from Studio B at present - the only real difference being the ability to do a separate Five. But, even assuming that Breakfast and the One could share a production team, that team is unlikely to be able to stretch into the late afternoon. Obviously, there is the production team for Sportsday, but that's a smaller team. In short, it's feasible, but I wouldn't particularly bet on it.

I would imagine it would probably be something like this:

That's quite plausible and similar to what I imagined, though ultimately probably better to take out one of the afternoon slots as well - I expect we're more likely to see at least one slot extended than one reduced in length.
