Why not pick the bike that you think has the best fit, then adjust the other to match it. I still say you can't trust geometry charts. If you're sure that saddle heights and setbacks, from the BB center, are the same, then do whatever is practical to make one bike about the same as the other. Since stems mostly come in 10mm increments and angle changes the horizontal reach, you may not be able to get them the same.
I had a Colnago and LOOK with that problem, I made the reach from the saddle to the bars the same, but one had a little more saddle setback than the other. It wasn't a big deal.
From what you've posted, a 110mm -17 stem would fix most of the issues. I know that someone makes a stem that's around -21.
