United States Executive Council

[President Punxsutawney Phil]

What if the US had a New Hampshire-style executive council to temper the power of the President, with Electoral Votes serving as the units from which districts were drawn? Deviation +/-10%, or more if absolutely required to keep states whole.
Under this arrangement we could have a total of 3, 5, 7 or even 9 districts. How would district magnitude affect the districts and regional representation? Etc.

[President Punxsutawney Phil]

Specifically, you could probably get something approaching a 10% deviation by splitting the 9th Circuit in half; keeping the 4th, 5th, 6th and 11th Circuits as they are; splitting the 8th Circuit between the 7th and 10th; and making two districts out of 1st, 2nd and 3rd circuits.

This would still likely require splitting California and New York, though. Eyeballing it, it might be plausible to do the former with one district for Arizona, Nevada and southern California and the other for northern California and the rest of the west. For the latter, the best split would probably be NYC, CT and NJ on the one hand, and New England, PA, DE and Upstate on the other hand?

Is this being done under a 7 district arrangement or a 9 district one? Or even 11?
All the states in the 9th together have 105 EVs.

Here are EV totals for all the circuits:
1st: 23
2nd: 39
3rd: 37
4th: 55
5th: 52
6th: 53
7th: 41
8th: 43
9th: 105
10th: 36
11th: 54
