You need to read through the Exchange DR whitepaper located at

In short, yes you would see pain trying to restore your database from the
Atlanta server to your Washington server, assuming the Washington server is
actually a live server with user data.  And vice versa.

Database replication as you¹re describing is an inherently expensive
operation; the cost of bandwidth is usually the killer on such projects, as
you¹ve indicated.  A better approach might be to have two ³warm² servers
standing by to receive a restore in each location in the event of a
catastrophic event.
