I have a prototype I've been playing with that allows two filters to be rotated independently from each other, I've been using it with the 15-30mm, a 150mm square GND and a 150mm square CPL. The only issue is, in it's current form, it vignettes quite heavily at the wider end, I've got some work to do to make it more compact.
In what format can you save your work, for sharing? My intention is to analyse the mounts already made by other manufacturers and take it further.
For me 180mm filters are overkilled overkill, because i use aps-c and dont plan on going full frame for the time being, but plan on buying the upcoming 11-18, so it should have somewhat similar needs.
If you are up to it we can share and develop filter holders in parallel, it would sure be a lot of fun to continue each others designs when we get stuck.
