One of the options raised is for BBC Scotland to 'top and tail' the show, with London doing the national and international news. Which almost sounds more complicated than just letting Scotland get on with it, to be honest. It's not the worst scenario - presumably it would deal with the England and Wales issue and allow Scotland to raise stories normally relegated to the regional slot to prominence - but it's hard to see it pleasing anyone.
I have to say I'm coming round to the idea - esp given the comparison of Scottish versions of national newspapers, which make sense.
I wonder what formats have been trialled or are being tested? I also wonder if you retain the name 'Reporting Scotland' at all, as they would no longer be just reporting on Scotland, and people will also associate it a lot with what's come before.
Getting into pure imagination, one thought that popped into my head was this London/Glasgow split, and if you could do a Newsday style of dual presentation without it coming across as too confusing or gimmicky, with BBC Scotland having a dedicated presenter somewhere in NBH, and they switch between presenter depending on the type of story. This might even please Scottish MPs who are down there Monday to Thursday, and could be interviewed in person rather than DTLs. Would require significant resources at both ends though, so unlikely.
I just sometimes get this feeling during long opt-outs (IndyRef results, election results, even Sunday Politics and Children in Need) that I'm missing out on something when the network broadcasts one thing and Scotland does another. Maybe that's just me.
