I'd be lying if I said I'd looked into this at all but I actually am in favour of small, self-governed regions (which are then part of a larger country) as a general rule. I fully believe that doing so does give more of a voice to each individual citizen.

I personally think that the best thing for England, for example, would be to devolve regions and allow each to govern the day-to-day issues themselves with only the biggest national-and-international scale issues left to Westminster. So for example... you'd have a devolved City of London, a devolved Yorkshire, Lancashire, etc etc.
