You can try using VAM instead and with some tweaks the style is quite close to HS2. However VAM is apparently harder to pickup initially but has the potential to produce better renders than HS2.
From a commercial perspective, it's probably not a good idea to use Daz3D. There 3D adult gaming industry is flooded with games using Daz like 80% - 85% of them (rough guesstimate) and a Steam listing is often this elusive carrot that makes it all sound good in theory, but very little developers really profit much in the end.
I don't mean to sound rude, but so far based on your stated game numbers, it looks decent but doesn't really stand out. If you go the Daz3D route, you will be trying to compete in an avalanche of Daz titles that come and go.
