What you are proposing Kagemusha is gerrymandering by stealth.

"If EU wants to develop it self to kind of Federal state how can bigger states have more votes than lesser countries."

Same way every other democracy does it. California has more electoral college votes than Hawaii, New South Wales has more house of represantive votes than Western Australia etc. I'm failing to see what the problem is here.

A fundamental basis of democracy should be that everyone's vote is equal or near equal. I would be one who would lose out of this (dutch citizen) but I really fail to see how you can base any working democracy on anything other than one vote one value.
