Updated to Lollipop ( RUU ) method, but Titanium Back was in Internal Storage topic

Updated to Lollipop ( RUU ) method, but Titanium Back up was in Internal Storage., however I did make a nandroid back up in TWRP which is saved in External

Can I make a back up of 5.01, go back to 4.4.4 via TWRP restore, run titnaium > save in external, and TWRP restore back to 5.01 and restore apps via Titanium

Any other adv?
