Personally, I'd call in a structural engineer and get him to tell you how you can convert those ties into collar ties, as in the image that you posted. I don't see why it can't be done, but the only issue is how far up you can place the ties, and what dimensions you need for them. Only a structural engineer can tell you that.
I would not go with the idea of allowing the tie bars to penetrate the inner leaf, because if I recall correctly, you guys need fairly high levels of isolation, right? It would be really hard to get that with parts of the outer leaf penetrating the inner leaf... unless you were to soffit around them, but that would be complex and expensive.

Really quick question before I get a chance to update this thread:
What is the best way to caulk an obtuse angle? There is plenty of info on internal angles, but I can't find this detail.
Put the backer rod in first, then the caulk on top.
Do you have a photo of the actual problem?

Okay, so it's basically the same process. Don't just overlap and butt joint?
