Adding in the effect that you've noted gives:
HTA: 73 becomes 77.3
Trail becomes 34
BB drop 100
That could be a bit exciting.
on a 98cm wheel base the 52mm drop with the smaller 650c wheel and fork results in a 3 degree increase in the HTA and with a 41 cm chain stay the BB drops about 22mm. so with a typical BB ground clearance of 268mm you end up with a BB clearance around 242-246mm - just on the edge of the 240mm UCI/UASC/USAT minimum. running instead two 650c wheels on a 700c frame you end up with the about the same frame drop (25.5m vs. 22mm) that "23" is trying to achieve, but with a bike that still handles properly and is actually aero. install a pair of Tektro R725 brakes (or a set with a similar 24-26mm drop) and you're pretty much set.
QED.
