Yep.... the tracks should import easily and they should all have the same starting point. You might not have to do a manual line up.

Should be interesting. I've done this on a few tunes now and then. Always fun giving new life to older songs and it's amazing what tweeking a few tracks can do. Also, do not forget to rework the "mastering and EQ" as you have probably learned quite a bit that will now make the entire project sound better.

post up some examples... before and after..... when you finish.
