One idea: you can make several *paralell* stairs, starting one on each side
- this way they never cross. Leonardo da Vinci used a similar idea in
Chambord's Castle main staircase, I think, some 500 years ago, and it is
still fantastic. Only his stairs were interior - for exterior use of the
same concept, there are the Pyramids and one of the theories for the way
they've been built (using "spiral" ramps).
Your concept is very good, overall; the advantages of exterior emergency
stairs seem obvious, and the spiral is a brilliant way to "cover" the whole
building economically.
