Ive never tried it but this is what I found on xda about it, also make sure you still have a good nandroid just in case.
[HOWTO] restoring settings and apps using titanium backup - xda-developers <~~~link to thread
This step is optional and can create some issues if done incorrectly. (Even if done correctly, it can sometimes cause issues.)
A: From the main screen of Titanium Backup press the button labeled: Backup/Restore at the top of the screen.
B: You will see a list of all the User Apps, System Apps, and System Data that are currently present on your phone. (The bottom of the list will have grayed out and striked items that are representative of data/apps that Titanium has backups of, but are not currently installed on the phone)
C: You will see different colors: RED - System App or Data (You Never want to restore these items); WHITE - User App/Data (These are almost always fine to restore, since they are not system dependent); GREEN - System data that is relatively safe to restore. I cannot say whether all the "Green" items are safe, but the Items I restore after a wipe are:
[BOOKMARKS]Browser - This will restore your bookmarks in the web browser.
[CALENDAR]Calendar Storage - This will restore your calendar appointments if they aren't saved to your Google Calendar.
[USER DICT] - This will restore the user learned words stored in your keyboards.
[SMS/MMS/APN]Dialar Storage & [SMS/MMS PREFS]Messaging - These will restore your messaging settings and conversations.
Wi-Fi Access Points - This will restore your "memorized" Wi-Fi access points, including password and log in credentials.
D: Feel free to play around with these and restore what "green" items you wish. But do so with caution and I recommend doing one at a time to ensure that you don't run into issues. Once you know what one's play nice, it will be a breeze to go through them in the future and restore the ones you want.
E:Restore an item by short pressing it. It will pop up a menu, and you select "Restore".
F: Reboot your phone!
