I'd go to the other end of the scale and say that no window is probably a better way. Open all year round, no one needs to go rushing in and no last minute panic buying or holding on till the very last minute in the hope that some sucker ups their price. You want a player? Check with his club, keep it to yourself and do it all behind closed doors. The transfer window is simply there for the media to stir [oops] up while there's no football.
IMO that would just favour the big clubs even more. A unknown player comes good, and the small club can usually keep him for a season, but they'd be snapped up much quicker with no window
