Yes and no, it will work but not in terms of longevity. The circumference is just too tight. I am working on making the Pro coils with user replaceable abilities, so if we did go with cotton, that would have to be the inevitable route. threading with a gasket should seal it enough, but then comes in the cost. Aluminum is just too week to support the fine threads and pressed fittings might not be durable enough for drops.
A big 10-4 on flange-less, I was up until the sun came up last night discussing them. I'm thinking to keep the Nitro's separate and reviving the Platinum line. They were/are a cornerstone here so they deserve a place. I just don't like copying old work so it may bring a new line of cartos instead of using the easy way out
