I suspect that, particularly for something as small (in terms of revenue 
to the LEC) as a BRI circuit, you won't have much leverage to ask for 
anything 'off the menu', like diverse physical routing through the CO.

When you get to the point of dealing with the copper in the ground/on the 
pole, your options for route diversity are usually extremely limited 
(read: nonexistent).  Telco copper plant is usually based on large 
multipair cables from the CO on a specific route, so even if you managed 
to get them to commit to diverse routeing in the CO, the copper pairs will 
still be in the same cable bundle, entering your building and the CO at 
the same points.
