No, controlfile is irrelevant as long as you got your physical structure somewhere (eg. controlfile trace) and all your redologs intact. You just recover "using backup controlfile" then (which means whatever controlfile you got, ignore it's checkpoint progress and other SCN information). That way you can recover to any point in time, providing that you recover all online datafiles to consistent SCN (you can't open a database recovered until SCN 1000 when one file has checkpoint SCN 1200 for example)
