Well here's my attempt...

To talk you through....
WEEKDAYS
1800-1900 The regional and national news as is now - it works so why change it.
1900 I've Put Emmerdale and Corrie back to back Mon, Wed & Fri. Tuesday I've added a quiz (though may make that to an Emmerdale so that both have 4 eps each week) with the regional slot moved half an hour earlier than present on Thursdays which would be followed by a new style version of manhunt or a watchdog consumer style programme.
The biggest change is on Tuesday in my schedule, they have the rights to the Champions League, so there's no way around that, and I get sick (and I'm sure viewers do) of the Tuesday night filler shows every other week or so (especially as the viewers are so different to one another with football and fashion or something).
So I thought how about reinventing the Soccer Aid idea, and have famous footballers/coaches/celebrities and members of the public create a new football league (perhaps just a few teams - maybe 4-

who would play on Tuesdays when there is no Champions League (and if successful maybe creating matches for other times in the week on ITV4), but I'd like it to be covered by ITV Sport presentation and production team. I thought that it would be a good idea to secure the male audience (well mainly male) every week, and keep a continuous stream of football on every Tuesday instead of creating filler programmes.
2000. I wanted the 8pm slot to offer similar to what it does now. On Monday I put both Tonight editions into one, and would change it editorially to deal with tougher issues, much more like World in Action/Panorama of old and dispatches on channel 4.
Tuesday would have the football through the evening.
Wednesday, I felt that I would create an entertainment night away from Saturday with a couple of family comedies that could be replaced with one or two light entertainment/quiz show formats through the year.
Thursday would be for The Bill, I wouldn't want to cut down the amount of episodes, but I would use ITV3/4 (depending on if they changed the programme to scew it at more males than being a soap) to air another episode, or maybe a spin off.
As for Friday, I've freed up a 2 hour slot for 2 hour long dramas such as Midsummer or A Touch of Frost, or maybe airing movies (well movies that would fit into two hours with breaks added).
2100. Monday and Thursday are for drama series, as friday could be used for airing two 1 hour dramas instead of one 2 hour.
Tuesday is again the football.
Wednesday I've billed in a chat show and was thinking about moving a big named chat show to Wednesday at 9 (a bit like the old days of Des O' Conner tonight - even though that was on at 8, though I suppose they could be changed if there was a comedy/light entertainment to lead into the news with good ratings).
2200, of course would bring the new News At Ten that would start dead on 10 (unless there was a live event preventing it - though I'm thinking awards or sports rather than I'm A Celebrity). I would preferibly have more adverts airing in within the 9-10 slot and then go straight from the credits of the 9-10pm hour into the News At Ten with nothing but an ident.
I'd like a full half hour of news, and so the regional would take the 2230 slot.
2245 Would be a time to try and take the audience and experiment with them with the surving 10pm experiements such as Ann Widdecomme, Benidorm, maybe the new spitting image/2D/3DTV show that they're planning (or were), a new comedy/panel show for Wednesday (I've tried to build it up as a comedy line up as all other days were taken), and time to experiment with ITV2 commissions on ITV1.
As for weekends....
Saturdays & Sundays are pretty much the same as they are now and self explanitory, although like nowadays Saturday's timings aren't on the hour, thus they have their own timescale.
The only things that I've charged are moving Millionnaire to Sundays (as others have already done, and removed the Emmerdale).
I've moved the Weekend news to 2230, and at 2245 on Friday, Saturday and Sunday, I wanted to create a 45 minute entertainment programme, with games, guests, music (not so much a chat show, but free for all with a big named host, who would be entertaining of course).
I think I've waffled long enough, sorry if it's confusing, any questions?
