SendMsgCmdImpl - Reg.

Hi,
I have a requirement wherein I need to compose a XML order message and store it
in MSGSTORE table which can be later picked up by a scheduler job and sent to a
third party order management system for creating the order.
However I am not using ORDERS table to create the order in my application
database. I create the order in the local database and not the commerce
database. 

On looking into the implementation of SendXMLOrderCmdImpl I can infer that
ORDERS table is accessed in its code which I cannot use.
Can I use the SendMsgCmdImpl for this purpose by instantiating it locally and
execute it?

Can anyone help me out on this issue?

Thanks and Regards,
