Scotland isn't a region, it is a country, a country with its own legal system, education system and parliament. It is going to be a lot easier to provide Scotland with more devolution than for a regional authority that doesn't presently exist. But this must also necessitate the reduced role of Scottish MPs in Parliament, whether the Labour party wants it all not.
I honestly can't see why some strategy for more powers can't be drawn up for Scotland, Wales and Ireland prior to the next election and separate from process of devolved local English government. In my opinion It must also necessitate some reform of the existing assemblies/parliament in these countries so that they better integrate with Westminster, which means significantly changing Westminster itself.
The Labour government made an absolute mess of creating rival governments to Westminster and we are now seeing the consequences. Just to provide DevoMax to Hollyrood whilst excluding Scottish MPs from Parliament, would further distance Scotland from the rest of the UK and ultimately lead to calls for complete independence. I would scrap the house of Lords, create a second elected chamber and integrate that chamber into all four constituent parts of the UK's governance (which means its mobility)
In effect what you need is a huge shakeup of government in the UK that hasn't been seen for hundreds of years and giving the job to the rotten rot who currently occupied the House....well it just won't happen.....
As for Mr Salmond, he should be more proactive and positive towards suggesting reforms instead of pouring scorn on Westminster, which lets face it, isn't difficult to do.. the man is an idiot.
