If you use the 101/2mm cyls you can make a 3.4(+) w/ the SC crank. Since people are getting good at nikasil plating now, you could bore the 100mm cyls to 101.1 & get some J&E's for a short stroke 3.4? No? I think I've even seen 101.1s for sale somewhere but can't find them right now (might have been from American Air Cooled cylinders?)

Also, the distance from the wrist pin to the flat part of the piston (the edge for most 911s) is called "compression height". It is shorter on the 3.2 and 3.6 pistons which is why they can't be interchanged w/ the earlier ones.

I was told by several reputable builders that when rebushing the small end of SC rods, there is more than enough meat to bore up to the larger wrist pin if needed. It was also mentioned that you can easily bore the hole off center to make the rod slightly longer/shorter to adjust compression & deck height on an existing P&C set.
