procedural wingtips? ability to disable decouplers?

[Kerbal410]

I was mostly thinking of aero surfaces that attach to wings, but the curvature can be changed. this part could be used to replicate things like spiroid winglets, blended winglets, and, possibly, split-tip winglets, depending on how this would be implemented, if at all. the split-tip would depend on two different adjustable sides.

I know it would be pointless, but that's not stopping me.

why not just use existing parts for winglets? spiroid, in particular, are, as you can see below on a Falcon 50, would be a bit of a pain. having a part with a changeable curve would fix this.

 

blended winglets are somewhat easier, but the smoothness would be tricky for someone like me with mediocre skills in wing design.

a split-tip is easiest, and I'd be fine without this, but it would be nice to have it as one part instead of two per wing.

if no procedural winglet will be added, could we at least have the ability to disable decouplers? staging pylons accidentally is killing me
