Restore MS Exchange 2003 from database files

MS Exchange 2003, Standard, SP 2.
MS Windows 2003 Server, STandard, SP 1.
(or W2k3 server, standard R2).

I am conducting tests for restoring our Exchange Server in case of a catastrophe.

One scenario I am looking at is to restore Exchange with only the dtabase files.

i.e.: I have a new install of Exchange on a new domain and server (same names as the previous domain and server). The only files I have to work with are:
priv1.edb
priv1.stm
pub1.edb
pub1.stm.

Will it be possible to get Exchange up and running with the data from these files?

Any ideas would be greatly appreciated!
