Darius- The plans did link up, thanks to who ever "fixed" it. Now I can offer some better observations based on the plans as they are in the smaller but more complete bike version.
Front Center- Reads as 58cm. 58.5 is my min for no overlap with 170 arms and no fenders. Maybe add 1.5cm to allow 172.5 and fenders.
Reach- I see a lot of seat/bars difference in height. This does impact the feel of reach to the bars as wel as actual horizontal dimension. What is the 7.4cm based on?
Seat angle- You gain about 1cm per degree of change here. Could this go forward and the seat be set further back on it's rails?
Head End- the same 1 degree gets about 1cm of front center holds (with a rake change adding a little bit more if the trail is maintained) (I do like the 6.1cm trail, some prefeer a shorter trail, I don't)
Top tube- As mentioned an exchange between the stem and TT length is the most straight forward way to increase Fc with out any other changes.
Chain Stay- Not asked about but my question is that if you do have a short torso and then need a short reach to the bars (which BTW might be more flexibility ditermined then body dimension ditermined) the you'll have more rearward a weight bias. So maybe a touch longer stays to keep the center of gravity ballance better. Just a thought here.

I assume you have been fitted on more then one bike and recorded those numbers then applied this knowlege to your new design. The two images on the link don't match. Is one a first version and the other a revision? Andy.
