Its possible but I don't think the Omega is good for any of the rebuildable atomizers or
tanks
I just put my Phoenix (14mm) on my Omega (24mm) and there is only a 5mm ledge on each side
I can push the button but it is not comfortable on the thumb
The well rounded edge on the Omega button doesn't help either
Most DID clones are 16mm so there will be even less room on the button (~4mm ledge)
