I guess you want to limit it to post-19th century Creationists, I don't think any of us would dismiss the contributions of Agassiz, Owen, Cuvier, Lyell, etc.
Since then, yes, the field has been rather bleak.
A poster on the IIDB evolution/creation board brought up the point that the man responsible for transplanting the baboon heart into that little girl (baby Faye?)rejected the idea of using a chimpanzee heart because he did not accept the evolutionary logic that chimpanzees were more closely related to humans than baboons. I don't know if a chimp heart would have worked, but the episode is illuminating nonetheless.
