Challenge: Is it possible to consolidate two separate SMS db files?

Hey everyone! So odd thread title and request, I know. I've searched MacRumors up and down and Google'd on how to do this to no avail.

Basically, on the 22nd of July I was sending a picture message to a friend when I suddenly got another text message from someone else, instantly causing my phone to turn off and restart. Afterwards, everything seemed fine until I clicked on the Messages app to find out that literally every text message I had accrued on my iPhones since 2007 had been wiped clean. I should have restored from a backup right then and there, but, like an idiot, my most recent backup was more than 2 weeks before that, making for a considerable loss of messages if I did.

So now, I have a number of iPhone backups throughout different days stored on my Time Machine backup and 4000-some new texts accrued since July 22. I've downloaded PhoneView and know that it gives me the ability to save all those 4000 most recent texts unto my computer, but is there a way I can combine those 4000 and all my texts before that that are still in my iTunes backups together and effective make a single unified sms database again so that it'll be as if nothing happened when I open my messages app? I'm prepared to jailbreak if need be. Would really appreciate some wise advice. Thanks guys

 

So not possible then guys? If it is that's okay, I just want to know before I revert to my old backup to salvage my (older) texts and dump my newer ones...thanks
