Is a orbit possible where 2 objects going in opposite directions can intersect repeatedly with minor course corrections?

I'm not sure I see the point to this question, but if one of the orbiting objects is hollow and you allow for course correction, then yes, one object passing through the other is possible.

I don't see what force would keep the object with a hole in the middle properly positioned so it was in effect perpendicular to the movement of the other objects. There's also problems with the orbits lining up just right rather than missing and giving each other a gravitational push, and with gravitational perturbations from the sun and the moon. A system like that would be a lot easier and require less adjustment if the Sun and Moon weren't there.

You'd probably want both orbits to be over the equator to reduce fluctuations, but eliminating fluctuations would be impossible. Every orbit would probably require some adjustment, and while it's theoretically possible, I'm not sure I see why anyone would want too - apart from perhaps it would look cool.
