Change from WuTang+Geo to Debug w/o losing backups?

I installed WuTang+Geohot as soon as it was made available and positively tested by the users here. I have all my 20 games in there, but signing packages has become a hassle so I was wondering if there is a way to go from my 3.55 WT+Geo to Kmeau or Debug without having to re-backup my games or lose my saved games?

Can I just go to "update" and select Kmeau CFW?
