Scripting Create Stored Procedure to create backup copy on same database

Hello,

I need to create a backup copy of a group of stored procedures on the same database.  Using TSQL I need to find all stored procedures that meet a criteria (WHERE pr.name = '%_SomeSuffix') and create that same procedure in the same database with a different name ('%_SomeSuffix_BAK).

Finding the stored procedures I need is easy

SELECT     
	pr.name ,    
	pr.type_desc ,    
	pr.create_date ,    
	mod.definition
FROM sys.procedures pr
INNER JOIN sys.sql_modules mod ON pr.object_id = mod.object_id
WHERE pr.Is_MS_Shipped = 0
AND pr.name LIKE '%_SomeSuffix'

Is there some way to do this?  Or do I need to export the stored procedures and do some string manipulation? 

Thanks,

Nick
