So, entrance duct would sit beside the step on the left and beside the 
pitot on the right.  Have you considered dropping the lip of the left 
duct and building it up strong enough to be the step?  Will the 
proximity of the right opening interfere with the pitot and throw off 
your airspeed and/or altitude readings?  Possibly eliminate that 
possibility with a tail mounted pitot like Tom Bauer's?  Will your exit 
duct start just aft of Station 4, with the bottom curving up just above 
the raised main wheels?  I'd be very interested in seeing how you route 
the duct through the baggage compartment.  The convoluted ducting that I 
kept coming up with was the biggest factor in pushing me to look at 
other solutions.
