Concerning blocking powers, the way this particular proposal deals with the problem is through cross-voting. Because TC senators will need GC votes as well to get elected, they will have a vested personal interest in not appearing intransigent and uncooperative. So the system would self-regulate, and blocking powers would only be used on issues that are really critical to the TC community.
Hmmm . Who will decide what the election system will be in each state? You said that the systems of both states should be harmonized, does this mean each state will not be allowed to change its own election systems?
Will it be "apli analogiki", in which case that 25% will trully always count as 25%?
Also can you explain this a bit more:
The Presidential Council will be elected directly by the People, from an integrated ticket, and with an Electoral College system based on the US Constitution. Each constituent state will appoint its own electors proportionately to population, but with each state having no less than 40% of the total electors.
Concerning what you, as a GC non-refugee, "will have to gain" from the northern constituent state, here follows a list:
a. You could opt to buy a home in the north after 7 years have elapsed.
b. You could opt to become a permanent resident of the TC state (even if you haven't yet purchased your own home, since property and residence are separate issues), and enjoy extended political rights as well as guaranteed education for your children under the Federal Government.
c. You could opt to work in the north, returning to your permanent residence in the south for weekends.
d. You could opt to have your holiday home in the north, in any region which you find attractive (see "point a" above).
I see. Well, apart from the possibility (very low one since I am not refugee) of getting some political rights in the north, I don't see any other difference between the north state of my own country and any other EU country. Most of the other "advantages" are due to the proximity of the two states than anything else. (if we had borders with Italy I could do most of the things you said).
It would be much easier to accept your plan if it was part of a specific transitional period, or if the amount under the TC state was much closer to their population percentage.
