Do you have any non-companion romance options in mind, you'd like to see in Divinity?
I'm not entirely sure what this has to do with specifically "Non-companion" things.
There very well could be Orc companion(s) in Divinity. Which could have romance options available.
The only notable aspect that would lead into "Non-companion" would be characters whom don't have aptitude for combat, thus are unable to be companions.
For example; Kelly Chambers and Samantha Traynor from the Mass Effect series. They were not suited for combat roles and thus couldn't go with you on missions.
