Hi Guys, I hope this is the right section for this, I wasn't too sure

Somebody has asked me if I can convert a theme from Nuke back to standard phpbb template as they use a normal phpbb board. I am not sure how this is done, I know that the phpbb templates that Nuke uses are ported from standard phpbb. Could anybody point me in the right direction please ? Or is there a theme conversion available to do this ????
