I have Ambicoi, Lee, Hoyarex and Cokin fiter holders, I hear there is also a
crew called Lucroit ..

My first thought - cut a sheet of aluminium to fit whichever filter system I
wanted, and decide which will be the minimum round filter size I will use.
Let's say 55mm.
Next I'd grab a 55mm skylight filter and remove the glass. Pop the filter
over my appropriately cut sheet of aluminium and mark the dimentions, grab a
hole saw and drill out the hole, speray the aluminium sheet black and epoxy
the now-empty skylight filter into place.
job done
If I have different sized filters to go on, I'd reach for the stepping
rings.
that work?
