I have most combinations of people and positions I think. A few outstanding gaps, and a really big question mark over what it takes to get Khdarr into a Law position.
Chapadoc has always given me a firm no, at least.
It’s possible to get Radomil. I called out his surfer facade by saying I was a liar too. He has the best Galactic Relations (60) out of anyone I’ve found so far, though the tests to coerce him seem too hard for an early pick up. He’s really not happy about it, and likely spends his time lining the mood wheel with assassins if you do force him to stay close.
