Suspect not - due to the odd and inconsistent selection of via points 
that people use, I suspect this would produce poor results.

One strategy might be to run the routing algorithm again, rejecting a 
route as soon as more than (say) 50% of it is the same as the 
previously-calculated optimal route.  Or to calculate all possible 
routes (since I believe they're pre-calculating lots of their data, they 
presumably have this option), sort by how optimal they are and then do a 
pass selecting routes with significant differences but without too much 
disadvantage compared to the optimal route.
