All characters important enough to have multiple conversations should get one. As well as those who are traders. And then those who are important for some bigger side-plot like Brasswhisper
Chaplain can replace Doloroso so he could get one
Vizsier could use one
Dargonus nobles need portraits, at least family heads. And Clementia obviously. She is really important
Muaran should get one, especially if Craftworlders and Crude Rock will be involved in either of those 2 dlcs
Maybe Malice too
