While possible and often a main factor for a "hi and back again" of assets, Ocean is one of the developers who changes a lot around. Normally if in WIAB or SG a similarity is there, this is with intent. See Aziz Revera, who is clearly a hommage for a late famous bodybuilder.It could be Daz assets are expensive and get reused a lot.
If both Beanpole and Kati were minor side characters, that would be no big thing. But Kati is a major character in WIAB, the prequel of SG.
