I think this may be a solution if I correctly understand the problem.

 

I modified the blocks in your drawing so that each is on a different layer and I added a crosshair for the two eccentric circles and a smaller circle at the center of the green and blue larger circles.

 

Since the center of the larger blue circle should be centered with the smaller of the green circles I added a parametric concentric constraint. This will ensure that the two block maintain a common pivot.

 

The process (use my "start" file):

 

1. Since the target is further from the center of the blue block than the blue crosshair, I want to rotate the green block clockwise to shorten this distance. An angle of about 15° is a good first guess.

 

2. Now rotate the green block counterclockwise about its center to bring the blue crosshair inline with the target.

 

Another iteration or two should place the blue crosshair pretty close to the center of the target.  

 

Refer to the "soln" file.

 

There may be a way to to automate this using numerical methods.
