Generally, this is not a good idea. An enlarger lens must reproduce accurately from a close, flat field (film) to another close, flat field (paper). The requirements on a normal camera lens are not so stringent in that it must reproduce from a far, not so flat field (scene) to a close, flat field (film). This allows the camera lens designer to design for other desirable characteristics such as speed. This is why using a camera lens for enlarging is generally not a good idea. An excellent macro lens designed for close, flat field reproduction can be used to excellent effect, but there's still the mount problem.
