well if its just a simple message below <20k then sure, but if its an item with an attachment, the Storage processes (storageOnlineOpns for example) are the only ways to re-attach the DVS+DVSSP etc, the Valkyrie does not include the logic to recombine these items into a MSG file, so you would just get the message body at best (if it does open)
