Why is Belkar's list not completed? I think Belkar would be the male member of the order most open to a same sex relationship - he had no problem kissing V despite not knowing V's sex, and also enjoyed imposing sexual banter on Roy (he even said that he was more comfortable with such banter than Roy becuase he was more secure in his masculinity).
Also on the subject of Belkar, I think he would be higher up on most other people's lists than you do. I'm guessing that you were surprised that Durkon had his as high as four, yet Durkon is the member of the order most diametrically opposed to Belkar in terms of alignment. Those closer to his alignment (everyone else) might have him higher still.
