Think that the 'Save Messages' functionality first introduced on 4.3 may be helpful for you.
SMS >> Hard Menu >> Save Messages
Select only the threads you want to merge and do the backup.
A XML file will be created. Now locate the file and send it to a desktop for better editing. I recommend Notepad++.
You will see that the XML content is a very simple markup code. I'm sure that after 2 minutes of attention you will know exactly what to do to merge the threads.
Hope this help somewhat.
