The stellar forge can create planets that are way out of kilter to the "plane of the star system". But it's usually because the proc-genned pseudo-history of the system is that another star has swept through, putting the planetary orbits through the proverbial blender.
You can see some interesting highly inclined orbits in
the Interesting Orrery thread.
But I can't say I've seen a case much like the one int he liked article, with a family of outer planets orbiting a binary star at 90 degrees to the stellar orbital plane. It does seem to me that such a system would be more stable than the usual one you find in ED, where the outer planets are all in the same plane as the binary stars. This one, for instance, cannot be truly stable, from an n-body-problem point of view:
The outer planets in the above system are simply too close to the two stars, the gravitational actions of the two stars individually would wrench the orbits to pieces. It's stable in ED, because it renders the planets as orbiting the AB barycentre, which it treats as a point mass from the point of view of the planets that orbit it.
