I'd say try to compile the document with things that are actually realistic. Many of the suggestions here are akin to having a meeting with Obama and telling him 'Shut down the military and divert the money to solve world hunger!' and similar statements that may sound good but in reality aren't going to be taken seriously. If you send through a document to Ballmer saying he should drop .NET, throw away Windows Phone 7 and base Windows on Unix, he isn't going to be likely to take any of your suggestions seriously (even if you did throw in ones that were realistic and made sense). I'm sure you already realise this, given you're smart enough to have been asked to produce such a document, but focus on slightly smaller things that could actually make a difference.
