Schema Extraction For Multiple Interdependent Databases

I'm looking for a tool that can extract only the schema from a database
in a form that can be used to generate that schema in another empty
database. This is to facilitate our disaster recovery processes where
we need the objects only, not the data, and need to replicate this to
our disaster recovery site over the WAN. There are plenty of tools
that can handle a single database, but does anyone know of any tools
that could handle multiple databases where many of the objects (stored
procs and views) are dependent on objects in other of the databases
(tables). This is a home-grown ETL suite so making changes to the code
to remove these dependencies would take way too much effort. I am
looking for something that can either extract the schema for all 3
databases and handle the object creation ordering to account for the
dependencies (a simple method would be to extract by object type across
all databases, e.g. tables for all dbs before views before procs), or a
backup/restore tool that allows you to restore the objects only without
data. Worst case we could write something to generate the DDL or use
SQL DMO, but ideally we would prefer to purchase a (relatively
inexpensive) tool to do it.

Thanks,
Simon
