just bought this Sigma EM-140 DG flash ... anybody tried to put a ringflash onto a reversed lens ?!

You could take a rear cap, the kind that twists on, cut the center out of it and glue on a step-up filter ring that matches the size of the ring flash.

Pentax actually used to make a ring light holder for reversed lenses. Good luck finding one. One of our fellow forum members came up with this solution:
