Some have done it. Kurt Wise went into graduate school as a YEC. He studied under Stephen Jay Gould, and graduated with his YEC beliefs intact.
However, Kurt Wise doesn't pretend that the evidence is on his side. He freely admits that the evidence is on the side of evolution and an old Earth.
"
Plesiadapus primate series,38 and the hominid series.39 Evidence for not just one but for all three of the species level and above types of stratomorphic intermediates expected by macroevolutionary theory is surely strong evidence for macroevolutionary theory. Creationists therefore need to accept this fact. It certainly CANNOT said that traditional creation theory expected (predicted) any of these fossil finds."
