Oddity is one of the ones that is a bit delicate here. I would suggest letting the offsets size up a bit before moving them. I have problems with my Oddity's rotting from too much water or drying out from too much sun. Fortunately I found just the right spot that never gets sun and gets limited water and they do well there.
As a suggestion, why not carefully remove the biggest one by cutting its stolon and transplanting it. Don't dig or disturb the rest of the plants with the wet seasons upon us. See how well that one does for you while the others are getting bigger. I've not noticed any problems with Oddity overcrowding itself - they seem to play fairly well with their siblings.
Just my opinion on this one. I try to leave mine alone as much as possible, due to some earlier failures with it.
