I'm able to get down to about 19-20mm with a similar "trick"
I have a Breakthrough Photography 77mm Dark CPL with a 77mm Xume filter adapter attached and run a very thin strip of gaffer tape around the circumference of the Xume adapter. I push this into the lens hood and I can get to about 19mm or 20mm without vignetting. I try to stick to 20mm so I do not damage the lens. Alternatively, I have 77mm MRC B&W Slim CPL with Xume attached (plus gaffer tape) which works in the same way but is a good option in the event I have a rear ND filter installed. I only just tried this out but it seems to work. So my options now are: Rear ND down to 14mm, ND + polarizer down to 19mm.
update: I think I may have used 2 strips of gaffer tape, one on top of the other.
