I agree. It'df definitely work for the Euros and in terms of the WC I'm sure something could be worked out with the confederations that have different season times. Apart from anything else its more tournament style would help players get used to each other and prepare in a way that'll be relevant when the tournament actually arrives.
Problem is the big clubs in Europe make a fortune going on summer tours to places like the US and Asia (under the guise of 'pre-season training').
