But the reservoir membrane would require a new tool for it. That's why I find it kinda unlikely. It's not a problem as long as we're talking about O-rings, but when custom seals come into play it becomes a bit different. Not impossible, a new tool (to cover different molding characteristics of a different material) is a few grand at most and most prototypes cost more than that, but still... I guess we'll find out sooner than later.
