In my little world, I'd often thought about a Northern 'Premier' service. Using the 14 Adelantes, with all other operators properly compensated of course, you could create a circular (or two pronged) service from Nottingham, as it seems to have crap connections north.
First service - Nottingham, Chesterfield, Sheffield, Leeds, York, Thirsk, Northallerton, Darlington, Chester-le-Street, Durham, Newcastle, Morpeth, Alnmouth, Berwick, Dunbar, Edinburgh.
Second service - Leeds, Huddersfield, Stalybridge, Manchester, Bolton, Preston, Lancaster, Oxenholme, Penrith, Carlisle, Lockerbie, Motherwell, Glasgow.
You could join the two together between Edinburgh and Glasgow, with the Glasgow being extended back to Nottingham. To me, it seems like a sensible idea to give major towns like Huddersfield, Dunbar etc a good stable and regular link to places like Scotland, York and Leeds. With the 180s, you have 125mph top speed for the ECML, first class for a cheaper alternative to XC, EC, TPE and Virgin on their respective stretches as well giving a decent service throughout.

Although with regards to Dunbar, I wouldn't say no to FTPE running Newcastle to Edinburgh.
This is a good idea, but seeing as they have sh*t all spare stock at the moment anyway, and can't give their own passengers across the Pennines, in particular Cleethorpes - Manchester a decent service, it'd be plain stupid to do this and deprive them of further capacity. At a guess, you'd need three or four extra units to do that from Newcastle north.
Mind you, because it's such a stupid idea, someone at DfT will now go and suggest it
