Hi John,
I'm sorry, but i disagree with you on one thing. Of course if your'e
adding "robber pads" and rotate the ic 90 deg it sure work without
getting any bridging. 
But if you can't add any pads? Then i would do as i described using a
chip-wave, ofcourse, in a nitrogen wave solderer. I it find most logical
to run the ic with standard pads this way, then ofcourse i don't have
alot of experience in soldering smt with a wave solderer, but i've been
there.
