Moving macro adator further from housing???

What would be the effect of moving a 67mm macro converter 20 mm's further away from the camera? ( PT-EPO5L housing

I am in the process of making another macro lighting "ring of light" and I can cut a 67mm thread on the front of the front of the lighting ring.

Also if anyone out there has a 67mm macro converter could you please measure the total diameter of it and let me know stating brand and model.

Thanks

I would guess the only major issue would be some vignetting, this is actually quite obvious a difference if I mount an Inon 165 macro lens on my EPL-2 (with the clip on macro adapter) versus my Fiances EPL-3 which has the inbuilt 67mm threads. I need to be zoomed in much closer to the 45mm end of the kit lens on the EPL2 to get over the vignetting compared to the EPL-3. Ill let you know the dimensions of the lens when I finish work.
