Be carefull with that! Two isues:

1.) Do not restore online redo logs from your cold backup!
2.) Do not restore controlfiles from your cold backup and do not backup your current control files to trace. No need for this, simply leave them as they are now and use them in the recovery.

It is obviously you will have to do point in time recovery (up to the point where you dropped the SYSTEM tablespace). So when you are done with the applying redo logs you will have to open your database with RESETLOGS option.
