In the DCQE such as the one referenced below:

1. The beta barium borate crystal (labeled as BBO) is placed after the double slit

Would the experiment still be the same if we place the BBO before the double slit and have the "signal" photon then proceed directly to Do without having to go through the slits.

the idler photon can however go through the slits.

Reference:

in the delayed choice quantum eraser, first performed by Yoon-Ho Kim, R. Yu, S.P. Kulik, Y.H. Shih, and Marlan O. Scully,[1]
