You can have synchronized spin with .5 and .7 g sections as long as their radii (radiuses) are in the same proportion. SM+13 for things with two or three largest dimensions is 150 yards, so the inner torus would need to be about 150*(.5/.7)=107 yards across, pretty close to SM+12 like you guessed.

Rotational gravity is radius times rotation rate (in radians per second) squared, so to get 7.7 yards/sec/sec on a 75-yard radius station, it needs to rotate once per 19.6 seconds.
