Yes, this is possible. To have a cylinder extrude along a spline you'll need at least a custom Start Mesh (Halfsphere's aren't builtin yet), then you can animate the FromTF and ToTF parameter to dynamically define the length of the extrusion. For performance reasons I would use a FixedF extrusion (it's usually the fastest). Adaptive results in less vertices, but requires more calculations.
