And this is why Halsin should just be out of the picture entirely, and a SH Karlach Lae'zel + Tav ( might as well add Minthara cuz why not) should just work instead.
I'd prefer they just keep them all mono to be honest, instead of adding diversity options. Normally I'd be completely fine with it, but I feel act 3 is already lacking so much content for just their mono paths. It makes me worried that if they were to add more options, they'd just spread their resources too thin and we'd just get more half baked romance stories instead of one full fledged one per companion.
