I don't mean to be a nay sayer- it's a solid way to continue without solving the problem so that you can come back to it. But... I wouldn't. Steering isn't something you want to mess with. Do a Google Image Search for "Scary Steering" and you'll find they all feature one major thing: bent tie rods as part of the design.
Yes, a pivot between them. Look up "steering idler arm" in a google image search to get an idea how they are used in the automotive world. For this application, I'd use an old American bottom bracket with one of the cranks cut down and used as the arm, and the BB used a the bearing. It's way overkill but perhaps you have parts on hand. Whatever you do, the geometry set by the steering arms themselves should be the pattern. The distance between the rotation axis and the tie rod mount should be the same as the kingpin to the tie rod on the steering arms and it should pivot in the same plane, ie have the same as the head tube angle.
In this picture, the red arms are all the same length and the blue angles are all the same:
But frankly, if it were me, I'd be fixing the underlying problem instead of adding complexity. Sorry :/
Hey that looks a lot better with a straight tie rod! Nice work It looks like you've got a lot of positive camber going on there. I don't know how that will affect handling. I wonder how hard it would be to reset the head tubes to compensate, and get back to the original angles? It's another one of those things that would be 1000x better to do now rather than later.
