I know about this problem too well -- it gave me quite a few sleepless nights in the shop. The way I got around it was simply to dremel hack a Century matte box so it now can handle lenses down to 16mm. Here's the mattbox I'm using: https://www.schneideroptics.com/ecom...=1390&IID=1770

Don't buy the Singh-Ray Variable ND filter at $400+ but instead buy the Fader ND from Light Craft Workshop at about $100 per filter. Then you can afford a filter for each lens (or at least four:-)
