Hi,
Maybe I can help you out, depending upon your needs.
I have never touched an Iscorama, but I am pretty confident it can be done.
Please take a look at some small anamorphic rehousings for single focus, which I have done: http://www.diehroptic.ch/albums/small-single-focus/
or bigger ones: http://www.diehroptic.ch/essays/2016/04/single-focus-for-moeller-rathenower-64-x2/
or overall mounting and adapting stuff: http://www.diehroptic.ch/albums/bolex-moeller/
or the Iscorama competition of some sort, like: http://www.diehroptic.ch/essays/2016/03/rectilux-collaboration-for-a-x15-scope/
Cheers
Alex
