Chris,
I'll admit I'm no expert on bike fit and geometry, but your 1st 3 bullets referencing the ground confuse me a bit. You have no control over BB height from ground, and the chances of it matching from one frame to the next, particularly with different builders, would seem slim? If everything measurement-wise matches in relation to the BB (i.e., your last 3 bullets), shouldn't you be good?
The standover height may differ, but shouldn't be much of a concern unless it is ridiculous. My Raleigh has always been "tight" down there, but has never been a issue.
